| Abstract Scope |
Lighter composite materials, as a fiber-reinforced polymer matrix, are well-suited to meet current demands for combining low-density structures with high mechanical strength. This pursuit has led to numerous investigations aiming to incorporate natural lignocellulosic natural fibers (NLFs) into polymer matrices. The present research proposes the use of sedge fibers (Cyperus malaccensis) as reinforcement in an epoxy matrix composite enhanced with graphene oxide (GO). The mechanical behavior was evaluated through Izod and Charpy impact. Morphological examinations of the sedge fiber-reinforced composites were performed to analyze fracture surfaces post-testing. The findings demonstrated a notable improvement when GO was incorporated into the epoxy system. For example, the group exhibiting the highest performance in the Izod and Charpy impact tests achieved values of 108.5 ± 12.22 and 155.51 ± 17.05 J/m, respectively. SEM images indicated that the agglomeration of GO nanoparticles and interfacial delamination were significantly minimized, suggesting a stronger fiber-matrix bonding. |
