摘要
碳纤维-铜复合材料是一种新型功能材料,它除了具有一定强度、刚度外,还具有导电导热性好,热膨胀系数小,摩擦系数小、磨损率低等许多优异性能,可用作低电压、大电流电机及特殊电机的电刷材料、耐磨材料及电力半导体支撑电极材料,集成电路散热材料等。本文较详细论述了碳纤维-铜复合材料的制造工艺,影响复合材料性能的因素以及此复合材料的几个应用实例,表明该复合材料是一种较有前途的新型功能材料。
Carbon fibre-copper composite is a new function material. Besides fairly good strength and stiffness, it also has the excellent properties of good electrical and thermal conductivity, small thermal expansion coefficient, small friction coefficient, low wear rate. It can be used as the brush material for low voltage large current motors and special motors, the wear resistant material, the material for semiconductor support electrode and IC radiating plate. The technology for carbon fibre copper composite production and the factors influencing the composite's properties were discussed in detail. Several examples of the application of this composite were given. It shows that the carbon fibre-copper composite is a new function material with a bright future.
