Abstract

Throughout the years, the use of composite materials has increased significantly, owing to its good properties such as lightweight, excellent energy absorption capabilities, and excellent corrosion resistance. In this study, the polyvinyl chloride (PVC) tube with the glass fibre reinforced plastic (GFRP) as the reinforcement were tested to determine the crashworthiness parameter under quasi-compression test. There were four type of configuration for PVC/GFRP composites tube; PVC tube without fibreglass, with 0º/90º, - 30º/60º and -45º/45º orientation of plain weave fibreglass. Thus, for each of the configuration type of composite tube, two different trigger mechanism were utilized that is composite tube without chamfer and with 45º internal single chamfer. The hand lay-up process was exploited for the fabrication of PVC/GFRP composite tube. From the finding, the reinforced PVC tube show better performance than the PVC tube alone. While, composites with 0º/90º oriented fibres parallel to the direction of compression had the highest specific energy absorption values, whereas PVC with no GFRP had the lowest specific energy absorption values. Thus, this study shows that by using trigger also can reduce the peak load value for all the specimen without drastically reducing the specific energy absorption value.
