摘　　要：对梯度基复合材料的力学性能,抗氧化性能,摩擦性能进行全面的测试与评价,分析微观结构与性能之间的关系。梯度基复合材料具有与C/C材料相当的力学性能和相似的断裂行为;它的抗氧化性能明显好于C/C材料;摩擦实验表明,C/C仍是最好的摩擦材料。Mechanical properties, oxidation resistance and wear resistance of C-SiC Gradient Matrix composites (GMCs) were studied. GMCs is comparable in fracture behavior and strength to C/C materials but the former have better oxidation resistance than the latter. The larger friction coefficient and wear rate of GMCs than C/C were observed in wear testing.
