Quasi-static Axial Crushing of E-Glass Fiber Reinforced Epoxy Composite by Different Number of Plies

The purpose of this study is to analyze the effect of the crushing mechanism on e-glass under various loading. To do so, cylindrical composites tubes are required to be fabricated as the specimen. To test the various variable that might affect the energy absorption of the specimen, the hand's lay-up process had been selected. Glass fiber reinforced composites tubes were fabricated with a fiber content of 1 to 3 layers. To evaluate the effect of the crushing mechanism of the fabricated composite tubes, a compression test was conducted. The effect of fabrication method and thickness of specimen were studied. In addition, the response of crush load–displacement, peak load, total energy absorption, specific energy absorption, and crush force efficiency were determined. Furthermore, the microstructure of all the specimens was analyzed using the digital microscope. As a result, it indicates that energy absorption capabilities are highly dominated by a higher reinforcement layers. H3 has the highest specific energy absorption which is 9.3 kJ/kg.
