| 摘 要： | 通过2D C/SiC复合材料的低速冲击试验和冲击后压缩试验,以及超声C扫描和红外热波两种无损检测方法,研究了冲击能量与冲击损伤的关系及其对压缩性能的影响.结果表明:C/SiC具有较好的损伤容限能力,冲击能量低于1.5J时几乎无目视损伤,高于9J时有被击穿的趋势.冲击后的名义压缩强度和压缩模量随着冲击能量的增加呈下降趋势,最多分别下降了44.7%和16.9%.

| Abstract: | Low velocity impact(LVI) damage behavior of 2D C/SiC composite was experimentally investigated.C/SiC laminates were impacted under various energy levels ranging from 1.5J to 9J by a dropping hammer.Impact damages were characterized by surface measurement and two non-destructive test(NDT) methods,which were ultrasonic C-scan and infrared thermal wave.The effect of impact energy on post-impact compressive performance was studied by static compress test.The results indicate that C/SiC behaves in a damage toler... |
