摘要
鉴于复合材料具有不同于一般材料优异的性能,因此有必要在宽广应变率的范围内(从准静态到冲击动态)来认识纳米粒子的增强增韧效应及其机理.为了对纳米橡胶/环氧树脂的动静态压缩力学性能进行研究,分别在霍普金森压杆(SHPB)和MTS液压伺服材料试验机上进行了纳米橡胶填充环氧树脂复合材料的动静态压缩实验,并将实验结果与细观力学方法的预测性能进行了比较分析,探讨了纳米级橡胶颗粒对基体材料环氧树脂的改性效果.
Nano-composites are provided with outstanding properties different from ordinary material, in some cases, materials maybe resist dynamic loads from explosions and high-speed impact. Consequently, it is imperious to understand the reinforcing and toughing effect and mechanism of nano-particles under broad strain rates （from quasi static to dynamic）. This paper has carried on some experiments of epoxy resin filled by nano-rubber particles through Split Hopkinson Pressure Bar （SHPB） and MTS, and have gained their mechanics properties. In the meanwhile, comparing the results of micromechanics, the modified effects of nano-rubber particles are discussed.
