【 摘 要 】
This research is purposed to study crashworthiness behavior of fiberglass tube subjected axial compression. The specimens are made of fiberglass and hand lay-up in different ply angles which are; specimen A ply angle is [(0/90)/(0/90)/(0/90)] specimen B ply angle is [(45/-45)/(45/-45)/(45/-45)] and specimen C ply angle is [(45/-45)/(0/90)/(45/-45)]. The tube has 50 mm outside diameter, 2 mm wall thickness and 100 mm length. Quasi-static test is done by ESH Universal Testing Machine with 10 mm/min of crushing speed. Impact test is done by Vertical Impact Testing Machine with the impact speed of 7 m/s. The result showed that specimen A gives highest specific energy absorption due to the vertical fiber orientation. In addition, the collapse mode and response of specimens to impact are also discussed in the paper.【 授权许可】
