SiC/SiO2复合涂层对碳纤维及其复合材料抗氧化性能影响研究
Study on the effect of SiC/SiO2 complex coating on the antioxidant performance of carbon fiber and its composite materials
摘要
Abstract
A SiC/SiO2 complex coating is prepared on the surface of carbon fiber by sol-gel method and precur-sor infiltration pyrolysis method,and carbon fiber reinforced phenolic resin matrix composites are prepared by using autoclave process,the flexural strength of the composites is tested after oxidation at 600℃,800℃and 1 000℃,studied the effect of coating on the oxidation resistance of carbon fiber and its composite materials.The results show that the flexural strength of complex coating carbon fiber/phenolic resin composites after oxidation at 1 000℃in air is 60 MPa,which is 3.3 times of the flexural strength of original carbon fiber/phenolic resin composites under the same conditions,and the good antioxidant effect of SiC/SiO2 coating on carbon fibers gives composite materials a certain flexural strength.And under the synergistic protection of SiC/SiO2 coating,the complex coating carbon fiber/phenolic resin composite material exhibits better ablation resistance under oxygen acetylene flame.关键词
