摘要
为了确定高应变率下复合材料的强度,本文利用分离式Hopkinson压杆研究了室温下应变率从10^(-4)s^(-1)变化到10^(-3)s^(-1)对国产环氧玻璃钢和聚酯玻璃钢的压缩强度的影响,为新型飞行保护头盔的设计提供了材料的实验依据。
In this paper, we investigated the change of compressive strength of chinese-made glss/epoxy and glass/polyester composites using the apparatus of SHPB when the average strain rates change from 10-4s-1to 10-3s-1. This paper provided material basis for the design of a new type of flight protective helmet.
