| 摘 要： | 在环氧树脂(EP)中添加纳米SiO2空心微球,制备添加不同比例纳米SiO2的EP浇注体和EP/碳纤维(CF)复合材料.经热重(TG)分析仪测试,发现添加纳米SiO2后EP的耐热性能明显提高,其中纳米SiO2质量分数为10%时其耐热性能最好;对有、无纳米SiO2的EP浇注体和EP/CF复合材料层板进行强功率激光辐照试验,结果表明,添加纳米SiO2空心微球能明显提高复合材料在激光作用下的抗烧蚀和隔热性能.

| Abstract: | The casting pieces of epoxy resin and epoxy resin/carbon fiber added by different content nanometer SiO2 particles are prepared.The results of thermogravimetric analysis show that the heat resistance of epoxy resin adding nano-SiO2 is obvious increased and 10% nano-SiO2 content is optimal.The epoxy resin/carbon fiber composite laminates with 10% nano-SiO2 as fillers are irradiated by high intensity laser.The results show that the addition of nano-SiO2 can increase the thermal protection and ablation propert... |
