| 摘 要： | 利用SHPB装置对UHMWPE交织双轴向纬编针织物/乙烯基酯树脂复合材料进行了高应变率压缩实验,研究了该材料的应变率效应和能量吸收.结果表明:等离子体处理后,复合材料的高应变率压缩性能有了较大的提高,放电功率100W是一个较为合适的处理条件.UHMWPE交织双轴向纬编复合材料呈现出一定的应变率敏感性:随着应变率的增加,最大应力、压缩模量、断裂应变能密度相应增大.由于交织双轴向纬编结构中的针织线圈及经纬纱交织作用,其具有较好的抗冲击性能.

| Abstract: | The high strain rate compressive properties of UHMWPE interlaced biaxial weft knitted(IBWK) fabrics/ vinyl ester resin composites were carried out in split Hopkinson pressure bar(SHPB).The strain rate effect and energy Absorption of composites were studied.The results indicate that the compressive performances of composites are improved after plasma modification,and 100W is an appropriate treating condition for discharge power.UHMWPE IBWK composite is a strain rate sensitive material in a certain extent:the... |
