Abstract

In this study, glass fibre reinforced (GFRP) polyvinyl chloride (PVC) tubes were subjected to quasi-static axial compression tests to determine their crashworthiness performance. To this end, this study employed GFRP/PVC tubes with four different fibre orientations, 45°, 55°, 65° and 90°. A five-axis filament winding machine was used to fabricate the tubes. The results show that there was a considerable increase in all crashworthiness characteristics due to GFRP reinforcement. For the GFRP/PVC composite tubes of different fibre orientations, the load-bearing capacity, crush force efficiency and energy absorption capability generally improve with increasing fibre orientation. The GFRP/PVC 45° specimen was a notable exception as it exhibited the best specific energy absorption capacity and a crushing force efficiency that was only slightly less than for the GFRP/PVC 90° specimen.

摘要

在本研究中，对玻璃纤维增强（GFRP）聚氯乙烯（PVC）管进行了准静态轴向压缩试验，以确定其耐撞性能。为此，本研究采用了纤维取向为45°、55°、65°和90°的GFRP/PVC管。使用五轴纤维缠绕机制造这些管子。结果表明，由于GFRP增强，所有耐撞特性都有显著提高。对于不同纤维取向的GFRP/PVC复合管，其承载能力、挤压效率和能量吸收能力通常随着纤维取向的增加而提高。GFRP/PVC 45°试样是一个显著的例外，因为它表现出最佳的比能量吸收能力，并且其挤压效率仅略低于GFRP/PVC 90°试样。
