Abstract

This study fabricated Kevlar-Hemp and Kevlar-Pineapple leaf fiber-based hybrid composites with different weaving architectures using the compression molding method. The quasi-static indentation behavior of hybrid composites was examined. The indentation behavior of hybrid composites was measured using peak load and energy absorption, load-displacement performance, and specimen damage size. The results show that the twill weave type Kevlar-Pineapple leaf fiber and Kevlar-Hemp fiber-based hybrid composites showed better energy absorption and peak load than all types of composites. Moreover, the hybrid composites exhibited beneficial results for peak force and absorbed energy than pure composites. After the indentation behavior, the front and back damaged surfaces of the composites were examined. The specimen damage size was assessed utilizing ultrasonic C-scan images. According to the findings, the hybrid composites’ surface damage was influenced by the different weaving architecture.
