摘　　要：测试和分析了热循环(20(?)300℃)中碳纤维/铜基(CF/Cu)复合材料的热膨胀行为。测定了CF/Cu复合材料在不同碳纤维含量、不同排布方向等条件下的热膨胀伸长,指出复合材料的热膨胀行为在不同温度区间的差异,主要是由于内部热残余应力的变化引起的。The thermal expansion behaviour of carbon fiber / copper-based (CF/Cu) composite material during thermal cycle (20 300℃) was observed and analyzed. The thermal expansion elongation of CF/Cu Composite material was measured under different carbon fiber conteat and arrangement direction. It has been pointed out that the difference of thermal expansion behaviour of composite matermial within different temperature ranges was mainly caused by the change in inner thermal remain stress.
