摘　　要：通过标准的冲击损伤试验方法,分别测试了两种不同碳纤维复合材料的损伤容限性能,一种材料为成熟的CYCOM977/12K HTS碳纤维复合材料,另一种材料为新研制的耐高温Epsilon 99702/HTS-130碳纤维复合材料。对比两种不同的复合材料层压板的损伤容限性能,分析它们的抗冲击能力的优劣性。试验表明,新型耐高温复合材料的抗冲击性能略高于前者,为飞机耐高温复合材料结构设计提供了一种合适的选择。Through the standard methods of impact damage test, the damage tolerance properties of two different kinds of carbon fiber composite material were tested. One kind is CYCOM977-2/12K HTS carbon fiber composite material, which is common;another kind is Epsilon 99702.1/HTS-130 carbon fiber composite material, which is newly developed high temperature resistant composite material. The damage tolerance properties of two kinds of composite laminates were compared, and the advantages and disadvantages of their impact resistance were analyzed. The experimental results show that the impact resistance of the new type of high temperature composite is slightly higher than that of the common;it is a suitable choice for the airplane design of high temperature resistant composites.
