| 摘 要： | 研究了编织C/C复合材料、针刺C/C复合材料和毡基C/C复合材料室温、高温的断裂韧性,以及3种不同增强体C/C复合材料的冲击韧性。研究发现,C/C复合材料的高温断裂韧性高于室温,其中针刺C/C复合材料的断裂韧性值最高。编织C/C复合材料的抗冲击性能表现出强烈的各向异性,针刺C/C复合材料抗冲击性能优于毡基C/C复合材料。

| Abstract: | The fracture toughness and impact toughness of three kinds of reinforced composites at room temperature and high temperature were investigated,including multi-directional braided C/C composite,needle punching C/C composite and whole felt C/C composite.The investigation results show that fracture toughness of C/C composites at high temperature is higher than that at room temperature,moreover fracture toughness of the needle punching C/C composite is the highest.The multi-directional braided C/C composite reveals strong anisotropy,and impact toughness of the needle punching C/C composite is superior to that of the whole felt C/C composite. |
