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.
