摘要

介绍了一种碳纤维/有机硅改性环氧树脂复合材料的性能研究情况.对该复合材料的力学性能、热常数和烧蚀性能进行了初步测试.结果表明,其拉伸强度达到558MPa,拉伸模量达到44.0GPa,层间剪切强度为16.6MPa,导热系数不超过0.3W/(m·K),氧乙炔烧蚀的线烧蚀率为0.049mm/s,质量烧蚀率为0.0595g/s.通过与常用的碳/酚醛材料比较,碳纤维/有机硅改性环氧树脂复合材料的性能较优.

Abstract

Mechanical properties,thermal constants and ablative properties of a carbon fiber/silicone modified epoxy composite were studied.Results indicated that the tensile strength,tensile modulus and shear strength of the composite were 558MPa,44.0GPa and 16.6MPa respectively.The thermal conductivity didn't exceed 0.3W/(m·K).The linear ablation rate and mass ablation rate of oxyacetylene was(0.049mm/s)and 0.0595g/s respectively.The performance of carbon fiber/silicone modified epoxy composite was better than that of carbon fiber/phenolic composite.
