INTEGRATION OF MACHINERY （From ELECTRICAL AND MACHINERY INDUSTRY）ABSTRACT Machinery was the modern science and technology development inevitable resultthis article has summarized the integration of machinery technology basic outlineand the development background .Summarized the domestic and foreign integration ofmachinery technology present situation has analyzed the integration of machinerytechnology trend of development. Key word：integration of machinery ，technology，present situation ，productt，echnique of manufacture ，trend of development 0. Introduction modern science and technology unceasing development impelleddifferent discipline intersecting enormously with the seepage has caused the projectdomain technological revolution and the transformation .In mechanical engineeringdomain because the microelectronic technology and the computer technology rapiddevelopment and forms to the mechanical industry seepage the integration of machinerycaused the mechanical industry the technical structure the product organizationthe function and the constitution the production method and the management systemhas had the huge change caused the industrial production to enter into quottheintegration of machineryquot by quotthe machinery electrificationquot for the characteristicdevelopment phase. 1. Integration of machinery outline integration of machinery is refers in theorganization new owner function the power function in the information processingfunction and the control function introduces the electronic technology unifies thesystem the mechanism and the computerization design and the software whichconstitutes always to call. The integration of machinery development also has becomeone to have until now own system new discipline not only develops along with thescience and technology but also entrusts with the new content .But its basiccharacteristic may summarize is: The integration of machinery is embarks from thesystem viewpoint synthesis community technologies and so on utilization mechanicaltechnology microelectronic technology automatic control technology computertechnology information technology sensing observation and control technologyelectric power electronic technology connection technology information conversiontechnology as well as software programming technology according to the systemfunction goal and the optimized organization goal reasonable disposition and thelayout various functions unit in multi-purpose high grade redundant reliable inthe low energy consumption significance realize the specific function value andcauses the overall system optimization the systems engineering technology .From thisproduces functional system then becomes an integration of machinery systematic orthe integration of machinery product. Therefore quotintegration of machineryquot coveringquottechnologyquot and quotproductquot two aspects .Only is the integration of machinerytechnology is based on the above community technology organic fusion one kind ofcomprehensive

technology but is not mechanical technical the microelectronictechnology as well as other new technical simple combination pieces together .Thisis the integration of machinery and the machinery adds the machinery electrificationwhich the electricity forms in the concept basic difference .The mechanicalengineering technology has the merely technical to develop the machineryelectrification still was the traditional machinery its main function still wasreplaces with the enlargement physical strength .But after develops the integrationof machinery micro electron installment besides may substitute for certainmechanical parts the original function but also can entrust with many new functionslike the automatic detection the automatic reduction information demonstrate therecord the automatic control and the control automatic diagnosis and the protectionautomatically and so on .Not only namely the integration of machinery product ishumans hand and body extending humans sense organ and the brains look has theintellectualized characteristic is the integration of machinery and the machineryelectrification distinguishes in the function essence. 2. Integration of machinery development condition integration of machinerydevelopment may divide into 3 stages roughly.20th century 60s before for the firststage this stage is called the initial stage .In this time the people determinationnot on own initiative uses the electronic technology the preliminary achievement toconsummate the mechanical product the performance .Specially in Second World Warperiod the war has stimulated the mechanical product and the electronic technologyunion these mechanical and electrical union military technology postwar transferscivilly to postwar economical restoration positive function .Developed and thedevelopment at that time generally speaking also is at the spontaneouscondition .Because at that time the electronic technology development not yetachieved certain level mechanical technical and electronic technology union alsonot impossible widespread and thorough development already developed the productwas also unable to promote massively. The 20th century 7080 ages for the second stagemay be called the vigorous development stage .This time the computer technologythe control technology the communication development has laid the technology basefor the integration of machinery development . Large-scale ultra large scaleintegrated circuit and microcomputer swift and violent development has provided thefull material base for the integration of machinery development .This timecharacteristic is :①A mechatronics word first generally is accepted in Japanprobably obtains the quite widespread acknowledgment to 1980s last stages in theworldwide scale ②The integration of machinery technology and the product obtainedthe enormous development ③The various countries start to the integration ofmachinery technology and the product give the very big attention and the support.1990s later periods started the integration of machinery technology the new stagewhich makes great strides forward to the intellectualized direction the integrationof machinery enters the thorough development time .At the same time optics thecommunication and so on entered the integration of machinery processes thetechnology also zhan to appear tiny in the integration of machinery the footappeared the light integration of machinery and the micro integration of machineryand so on the new branch On the other hand to the integration of

1．绪论

现代科学技术的不断发展，极大地推动了不同学科的交叉与渗透，导致了工程领域的技术革命与改造。在机械工程领域，由于微电子技术和计算机技术的迅速发展及其向机械工业的渗透所形成的机电一体化，使机械工业的技术结构、产品机构、功能与构成、生产方式及管理体系发生了巨大变化，使工业生产由机械电气化迈入了机电一体化为特征的发展阶段。2．机电一体化概要

机电一体化是指在机构得主功能、动力功能、信息处理功能和控制功能上引进电子技术，将机械装置与电子化设计及软件结合起来所构成的系统的总称。机电一体化发展至今也已成为一门有着自身体系的新型学科，随着科学技术的不但发展，还将被赋予新的内容。但其基本特征可概括为：机电一体化是从系统的观点出发，综合运用机械技术、微电子技术、自动控制技术、计算机技术、信息技术、传感测控技术、电力电子技术、接口技术、信息变换技术以及软件编程技术等群体技术，根据系统功能目标和优化组织目标，合理配置与布局各功能单元，在多功能、高质量、高可靠性、低能耗的意义上实现特定功能价值，并使整个系统最优化的系统工程技术。由此而产生的功能系统，则成为一个机电一体化系统或机电一体化产品。因此，机电一体化涵盖技术和产品两个方面。只是，机电一体化技术是基于上述群体技术有机融合的一种综合技术，而不是机械技术、微电子技术以及其它新技术的简单组合、拼凑。这是机电一体化与机械加电气所形成的机械电气化在概念上的根本区别。机械工程技术有纯技术发展到机械电气化，仍属传统机械，其主要功能依然是代替和放大的体力。但是发展到机电一体化后，其中的微电子装置除可取代某些机械部件的原有功能外，还能赋予许还能赋予许多新的功能，如自动检测、自动处理信息、自动显示记录、自动调节与控制自动诊断与保护等。即机电一体化产品不仅是人的手与肢体的延伸，还是人的感官与头脑的眼神，具有智能化的特征是机电一体化与机械电气化在功能上的本质区别。. 2、机电一体化的发展状况机电一体化的发展大体可以分为3个阶段。20世纪60年代以前为第一阶段，这一阶段称为初级阶段。在这一时期，人们自觉不自觉地利用电子技术的初步成果来完善机械产品的性能。特别是在第二次世界大战期间，战争刺激了机械产品与电子技术的结合，这些机电结合的军用技术，战后转为民用，对战后经济的恢复起了积极的作用。那时研制和开发从总体上看还处于自发状态。由于当时电子技术的发展尚未达到一定水平，机械技术与电子技术的结合还不可能广泛和深入发展，已经开发的产品也无法大量推广。20世纪70~80年代为第二阶段，可称为蓬勃发展阶段。这一时期，计算机技术、控制技术、通信技术的发展，为机电一体化的发展奠定了技术基础。大规模、超大规模集成电路和微型计算机的迅猛发展，为机电一体化的发展提供了充分的物质基础。这个时期的特点是：①mechatronics一词首先

在日本被普遍接受，大约到20世纪80年代末期在世界范围内得到比较广泛的承认；②机电一体化技术和产品得到了极大发展；③各国均开始对机电一体化技术和产品给以很大的关注和支持。20世纪90年代后期，开始了机电一体化技术向智能化方向迈进的新阶段，机电一体化进入深入发展时期。一方面，光学、通信技术等进入了机电一体化，微细加工技术也在机电一体化中崭露头脚，出现了光机电一体化和微机电一体化等新分支；另一方面对机电一体化系统的建模设计、分析和集成方法，机电一体化的学科体系和发展趋势都进行了深入研究。同时，由于人工智能技术、神经网络技术及光纤技术等领域取得的巨大进步，为机电一体化技术开辟了发展的广阔天地。这些研究，将促使机电一体化进一步建立完整的基础和逐渐形成完整的科学体系。我国是从20世纪80年代初才开始在这方面研究和应用。国务院成立了机电一体化领导小组并将该技术列为“863计划”中。在制定“九五”规划和2010年发展纲要时充分考虑了国际上关于机电一体化技术的发展动向和由此可能带来的影响。许多大专院校、研究机构及一些大中型企业对这一技术的发展及应用做了大量的工作，不取得了一定成果，但与日本等先进国家相比仍有相当差距。

3．机电一体化的发展趋势机电一体化是集机械、电子、光学、控制、计算机、信息等多学科的交叉综合，它的发展和进步依赖并促进相关技术的发展和进步。因此，机电一体化的主要发展方向如下：3.1智能化智能化是21世纪机电一体化技术发展的一个重要发展方向。人工智能在机电一体化建设者的研究日益得到重视，机器人与数控机床的智能化就是重要应用。这里所说的“智能化”是对机器行为的描述，是在控制理论的基础上，吸收人工智能、运筹学、计算机科学、模糊数学、心理学、生理学和混沌动力学等新思想、新方法，模拟人类智能，使它具有判断推理、逻辑思维、自主决策等能力，以求得到更高的控制目标。诚然，使机电一体化产品具有与人完全相同的智能，是不可能的，也是不必要的。但是，高性能、高速的微处理器使机电一体化产品赋有低级智能或人的部分智能，则是完全可能而又必要的。

3.2模块化模块化是一项重要而艰巨的工程。由于机电一体化产品种类和生产厂家繁多，研制和开发具有标准机械接口、电气接口、动力接口、环境接口的机电一体化产品单元是一项十分复杂但又是非常重要的事。如研制集减速、智能调速、电机于一体的动力单元，具有视觉、图像处理、识别和测距等功能的控制单元，以及各种能完成典型操作的机械装置。这样，可利用标准单元迅速开发出新产品，同时也可以扩大生产规模。这需要制定各项标准，以便各部件、单元的匹配和接口。由于利益冲突，近期很难制定国际或国内这方面的标准，但可以通过组建一些大企业逐渐形成。显然，从电气产品的标准化、系列化带来的好处可以肯定，无论是对生产标准机电一体化单元的企业还是对生产机电一体化产品的企业，规模化将给机电一体化企业带来美好的前程。3.3网络化20世纪90年代，计算机技术等的突出成就是网络技术。网络技术的兴起和飞速发展给科学技术、工业生产、政治、军事、教育义举人么日常生活都带来了巨大的变革。各种网络将全球经济、生产连成一片，企业间的竞争也将全球化。机电一体化新产品一旦研制出来，只要其功能独到，质量可靠，很快就会畅销全球。由于网络的普及，基于网络的各种远程控制和监视技术方兴未艾，而远程控制的终端设备本身就是机电一体化产品。现场总线和局域网技术是家用电器网络化已成大势，利用家庭网络(home net)将各种家用电器连接成以计算机为中心的计算机集成家电系统(computer integrated appliance system, CIAS)，使人们在家里分享各种高技术带来的便利与快乐。因此，机电一体化产品无疑朝着网络化方向发展。3.4微型化微型化兴起于20世纪80年代末，指的是机电一体化向微型机器和微观领域发展的趋势。国外称其为微电子机械系统（MEMS），泛指几何尺寸不超过1cm3的机电一体化产品，并向微米、纳米级发展。微机电一体化产品体积小、耗能少、运动灵活，在生物医疗、军事、信息等方面具有不可比拟的优势。微机电一体化发展的瓶颈在于微机械技术，微机电一体化产品的加工采用精细加工技术，即超精密技术，它包括光刻技术和蚀刻技术两类。3.5绿色化工业的发达给人们生活带来了巨大

变化。一方面，物质丰富，生活舒适；另一方面，资源减少，生态环境受到严重污染。于是，人们呼吁保护环境资源，回归自然。绿色产品概念在这种呼声下应运而生，绿色化是时代的趋势。绿色产品在其设计、制造、使用和销毁的生命过程中，符合特定的环境保护和人类健康的要求，对生态环境无害或危害极少，资源利用率极高。设计绿色的机电一体化产品，具有远大的发展前途。机电一体化产品的绿色化主要是指，使用时不污染生态环境，报废后能回收利用。3.6系统化系统化的表现特征之一就是系统体系结构进一步采用开放式和模式化的总线结构。系统可以灵活组态，进行任意剪裁和组合，同时寻求实现多子系统协调控制和综合管理。表现之二是通信功能的大大加强，一般除RS232外，还有RS485、DCS人格化。未来的机电一体化更加注重产品与人的关系，机电一体化的人格化有两层含义。一层是，机电一体化产品的最终使用对象是人，如何赋予机电一体化产品人的智能、情感、人性显得越来越重要，特别是对家用机器人，其高层境界就是人机一体化。另一层是模仿生物机理，研制各种机电一体花产品。事实上，许多机电一体化产品都是受动物的启发研制出来的。4．结语综上所述，机电一体化的出现不是孤立的，它是许多科学技术发展的结晶，是社会生产力发展到一定阶段的必然要求。当然，与机电一体化相关的技术还有很多，并且随着科学技术的发展，各种技术相互融合的趋势将越来越明显，机电一体化技术的广阔发展前景也将越来越光明。

五、外文资料翻译 Stress and Strain 1.Introduction to Mechanics of Materials Mechanics of materials is a branch of applied mechanics that deals with the behavior of solid bodies subjected to various types of loading. It is a field of study that i s known by a variety of names, including “strength of materials” and “mechanics of deformable bodies”. The solid bodies considered in this book include axially-loaded bars, shafts, beams, and columns, as well as structures that are assemblies of these components. Usually the objective of our analysis will be the determination of the stresses, strains, and deformations produced by the loads; if these quantities can be found for all values of load up to the failure load, then we will have obtained a complete picture of the mechanics behavior of the body. Theoretical analyses and experimental results have equally important roles in the study of mechanics of materials . On many occasion we will make logical derivations to obtain formulas and equations for predicting mechanics behavior, but at the same time we must recognize that these formulas cannot be used in a realistic way unless certain properties of the been made in the laboratory. Also , many problems of importance in engineering cannot be handled efficiently by theoretical means, and experimental measurements become a practical necessity. The historical development of mechanics of materials is a fascinating blend of both theory and experiment, with experiments pointing the way to useful results in some instances and with theory doing so in others①. Such famous men as Leonardo da Vinci(1452-1519) and Galileo Galilei (1564-1642) made experiments to adequate to determine the strength of wires , bars , and beams , although they did not develop any adequate theo ries (by today’s standards ) to explain their test results . By contrast , the famous mathematician Leonhard Euler(1707-1783) developed the mathematical theory any of columns and calculated the critical load of a column in 1744 , long before any experimental evidence existed to show the significance of his results ②. Thus , Euler’s theoretical results remained unused for many years, although today they form the basis of column theory. The importance of combining theoretical derivations with experimentally determined properties of materials will be evident theoretical derivations with experimentally determined properties of materials will be evident as we proceed with

Economic policy,tourism trade and productive diversification （Excerpt） Iza Lejárraga,Peter Walkenhorst The broad lesson that can be inferred from the analysis is that promoting tourism linkages with the productive capabilities of a host country is a multi-faceted approach influenced by a variety of country conditions.Among these,fixed or semi-fixed factors of production,such as land,labor,or capital,seem to have a relatively minor influence.Within the domain of natural endowments,only agricultural capital emerged as significant.This is a result that corresponds to expectations,given that foods and beverages are the primary source of demand in the tourism economy.Hence,investments in agricultural technology may foment linkages with the tourism market.It is also worth mentioning that for significant backward linkages to emerge with local agriculture,a larger scale of tourism may be important. According to the regression results,a strong tourism–agriculture nexus will not necessarily develop at a small scale of tourism demand. It appears that variables related to the entrepreneurial capital of the host economy are of notable explanatory significance.The human development index(HDI), which is used to measure a country's general level of development,is significantly and positively associated with tourism linkages.One plausible explanation for this is that international tourists,who often originate in high-income countries,may feel more comfortable and thus be inclined to consume more in a host country that has a life-style to which they can relate easily.Moreover,it is important to remember that the HDI also captures the relative achievements of countries in the level of health and education of the population.Therefore,a higher HDI reflects a healthier and more educated workforce,and thus,the quality of local entrepreneurship.Related to this point,it is important to underscore that the level of participation of women in the host economy also has a significantly positive effect on linkages.In sum, enhancing local entrepreneurial capital may expand the linkages between tourism and other sectors of the host country.

Advantages of Managed Code Microsoft intermediate language shares with Java byte code the idea that it is a low-level language witha simple syntax , which can be very quickly translated intonative machine code. Having this well-defined universal syntax for code has significant advantages. Platform independence First, it means that the same file containing byte code instructions can be placed on any platform; atruntime the final stage of compilation can then be easily accomplished so that the code will run on thatparticular platform. In other words, by compiling to IL we obtain platform independence for .NET, inmuch the same way as compiling to Java byte code gives Java platform independence. Performance improvement IL is actually a bit more ambitious than Java bytecode. IL is always Just-In-Time compiled (known as JIT), whereas Java byte code was ofteninterpreted. One of the disadvantages of Java was that, on execution, the process of translating from Javabyte code to native executable resulted in a loss of performance. Instead of compiling the entire application in one go (which could lead to a slow start-up time), the JITcompiler simply compiles each portion of code as it is called (just-in-time). When code has been compiled.once, the resultant native executable is stored until the application exits, so that it does not need to berecompiled the next time that portion of code is run. Microsoft argues that this process is more efficientthan compiling the entire application code at the start, because of the likelihood that large portions of anyapplication code will not actually be executed in any given run. Using the JIT compiler, such code willnever be compiled.

Inventory management Inventory Control On the so-called "inventory control", many people will interpret it as a "storage management", which is actually a big distortion. The traditional narrow view, mainly for warehouse inventory control of materials for inventory, data processing, storage, distribution, etc., through the implementation of anti-corrosion, temperature and humidity control means, to make the custody of the physical inventory to maintain optimum purposes. This is just a form of inventory control, or can be defined as the physical inventory control. How, then, from a broad perspective to understand inventory control? Inventory control should be related to the company's financial and operational objectives, in particular operating cash flow by optimizing the entire demand and supply chain management processes (DSCM), a reasonable set of ERP control strategy, and supported by appropriate information processing tools, tools to achieved in ensuring the timely delivery of the premise, as far as possible to reduce inventory levels, reducing inventory and obsolescence, the risk of devaluation. In this sense, the physical inventory control to achieve financial goals is just a means to control the entire inventory or just a necessary part; from the perspective of organizational functions, physical inventory control, warehouse management is mainly the responsibility of The broad inventory control is the demand and supply chain management, and the whole company's responsibility. Why until now many people's understanding of inventory control, limited physical inventory control? The following two reasons can not be ignored: First, our enterprises do not attach importance to inventory control. Especially those who benefit relatively good business, as long as there is money on the few people to consider the problem of inventory turnover. Inventory control is simply interpreted as warehouse management, unless the time to spend money, it may have been to see the inventory problem, and see the results are often very simple procurement to buy more, or did not do warehouse departments . Second, ERP misleading. Invoicing software is simple audacity to call it ERP, companies on their so-called ERP can reduce the number of inventory, inventory control, seems to rely on their small software can get.

10kV小区供配电英文文献及中文翻译

在广州甚至广东的住宅小区电气设计中,一般都会涉及到小区的高低压供配电系统的设计.如10kV高压配电系统图,低压配电系统图等等图纸一大堆.然而在真正实施过程中,供电部门(尤其是供电公司指定的所谓电力设计小公司)根本将这些图纸作为一回事,按其电脑里原有的电子档图纸将数据稍作改动以及断路器按其所好换个厂家名称便美其名曰设计(可笑不?),拿出来的图纸根本无法满足电气设计的设计意图,致使严重存在以下问题:(也不知道是职业道德问题还是根本一窍不通) 1.跟原设计的电气系统货不对板,存在与低压开关柜后出线回路严重冲突,对实际施工造成严重阻碍,经常要求设计单位改动原有电气系统图才能满足它的要求(垄断的没话说). 2.对消防负荷和非消防负荷的供电(主要在高层建筑里)应严格分回路(从母线段)都不清楚,将消防负荷和非消防负荷按一个回路出线(尤其是将电梯和消防电梯,地下室的动力合在一起等等,有的甚至将楼顶消防风机和梯间照明合在一个回路,以一个表计量). 3.系统接地保护接地型式由原设计的TN-S系统竟曲解成"TN-S-C-S"系统(室内的还需要做TN-C,好玩吧?),严格的按照所谓的"三相四线制"再做重复接地来实施,导致后续施工中存在重复浪费资源以及安全隐患等等问题.. ............................(违反建筑电气设计规范等等问题实在不好意思一一例举,给那帮人留点混饭吃的面子算了) 总之吧,在通过图纸审查后的电气设计图纸在这帮人的眼里根本不知何物,经常是完工后的高低压供配电系统已是面目全非了,能有百分之五十的保留已经是谢天谢地了. 所以.我觉得:住宅建筑电气设计,让供电部门走!大不了留点位置,让他供几个必需回路的电,爱怎么折腾让他自个怎么折腾去.. Guangzhou, Guangdong, even in the electrical design of residential quarters, generally involving high-low cell power supply system design. 10kV power distribution systems, such as maps, drawings, etc. low-voltage distribution system map a lot. But in the real implementation of the process, the power sector (especially the so-called power supply design company appointed a small company) did these drawings for one thing, according to computer drawings of the original electronic file data to make a little change, and circuit breakers by their the name of another manufacturer will be sounding good design (ridiculously?), drawing out the design simply can not meet the electrical design intent, resulting in a serious following problems: (do not know or not know nothing about ethical issues) 1. With the original design of the electrical system not meeting board, the existence and low voltage switchgear circuit after qualifying serious conflicts seriously hinder the actual construction, often require changes to the original design unit plans to meet its electrical system requirements (monopoly impress ). 2. On the fire load and fire load of non-supply (mainly in high-rise building in) should be strictly sub-loop (from the bus segment) are not clear, the fire load and fire load of non-qualifying press of a circuit (especially the elevator and fire elevator, basement, etc.

英文翻译英语原文： . Introducing Classes The only remaining feature we need to understand before solving our bookstore problem is how to write a data structure to represent our transaction data. In C++ we define our own data structure by defining a class. The class mechanism is one of the most important features in C++. In fact, a primary focus of the design of C++ is to make it possible to define class types that behave as naturally as the built-in types themselves. The library types that we've seen already, such as istream and ostream, are all defined as classesthat is,they are not strictly speaking part of the language. Complete understanding of the class mechanism requires mastering a lot of information. Fortunately, it is possible to use a class that someone else has written without knowing how to define a class ourselves. In this section, we'll describe a simple class that we canuse in solving our bookstore problem. We'll implement this class in the subsequent chapters as we learn more about types,expressions, statements, and functionsall of which are used in defining classes. To use a class we need to know three things: What is its name? Where is it defined? What operations does it support? For our bookstore problem, we'll assume that the class is named Sales_item and that it is defined in a header named Sales_item.h. The Sales_item Class The purpose of the Sales_item class is to store an ISBN and keep track of the number of copies sold, the revenue, and average sales price for that book. How these data are stored or computed is not our concern. To use a class, we need not know anything about how it is implemented. Instead, what we need to know is what operations the class provides. As we've seen, when we use library facilities such as IO, we must include the associated headers. Similarly, for our own classes, we must make the definitions associated with the class available to the compiler. We do so in much the same way. Typically, we put the class definition into a file. Any program that wants to use our class must include that file. Conventionally, class types are stored in a file with a name that, like the name of a program source file, has two parts: a file name and a file suffix. Usually the file name is the same as the class defined in the header. The suffix usually is .h, but some programmers use .H, .hpp, or .hxx. Compilers usually aren't picky about header file names, but IDEs sometimes are. We'll assume that our class is defined in a file named Sales_item.h. Operations on Sales_item Objects

University of Science and Technology Beijing and Springer-Verlag Berlin Heidelberg 2010 Preparation and properties of C/C-SiC brake composites fabricated by warm compacted-in situ reaction Zhuan Li, Peng Xiao, and Xiang Xiong State Key Laboratory of Powder Metallurgy, Central South University, Changsha 410083, China (Received: 12 August 2009; revised: 28 August 2009; accepted: 2 September 2009) Abstract: Carbon fibre reinforced carbon and silicon carbide dual matrix composites (C/C-SiC) were fabricated by the warm compacted-in situ reaction. The microstructure, mechanical properties, tribological properties, and wear mechanism of C/C-SiC composites at different brake speeds were investigated. The results indicate that the composites are composed of 58wt% C, 37wt% SiC, and 5wt% Si. The density and open porosity are 2.0 g·cm–3 and 10%, respectively. The C/C-SiC brake composites exhibit good mechanical properties. The flexural strength can reach up to 160 MPa, and the impact strength can reach 2.5 kJ·m–2. The C/C-SiC brake composites show excellent tribological performances. The friction coefficient is between 0.57 and 0.67 at the brake speeds from 8 to 24 m·s?1. The brake is stable, and the wear rate is less than 2.02×10?6 cm3·J?1. These results show that the C/C-SiC brake composites are the promising candidates for advanced brake and clutch systems.
