摘　　要：介绍了复合材料裙用纳米改性环氧树脂高模量体系研究。测试了纳米S iO2含量、分散处理方法对浇铸体的影响,确定了优选纳米改性环氧树脂配方。优选配方的拉伸模量、弯曲模量、压缩模量分别高达4.53 GPa、4.62 GPa和4.36 GPa。当环氧树脂用量为40%时,其织物复合材料具有良好的力学性能。SEM可观察到织物复合材料的压缩破坏断口呈纤维屈曲和层间分层的破坏特征。The study of nanometer modified epoxy resin system with high modulus for composite skirt was presented. Effects of content of nano-SiO2 and dispersion method on cast were tested, in the result, the composition of optimized formula was determined. The tensile modulus, flexural modulus and compressive modulus of the formula are 4. 53 GPa,4.62 GPa and 4.36 GPa, respectively. When the resin constent is 40% by weight, the fabric composite showed good mechanical properties. Fabric composite compressive fracture micrographs of SEN revealed the characteristic of fibre buckling and the delamination.
