摘要

Natural fiber–reinforced polymer composites are often limited by weak interfacial bonding and inadequate impact resistance, which restrict their use in high-performance applications. To address this limitation, woven Agave americana fiber–reinforced polyethylene composites modified with reduced graphene oxide (rGO) were developed and evaluated. Composites containing 0, 2, 4, and 6 wt% rGO were fabricated using vacuum bagging technique to ensure uniform fiber alignment and effective dispersion of nanofillers. Tensile tests were conducted according to ASTM D638, and low-velocity drop-weight impact tests were performed at impact energies of 25 J, 30 J, and 35 J, supported by scanning electron microscopy for morphological analysis. The results revealed that rGO incorporation significantly enhanced mechanical performance, with the 6 wt% rGO composite exhibiting a tensile strength improvement of approximately 5.50% compared to the unmodified composite. Furthermore, a maximum absorbed impact energy of 46.14 J at 35 J impact energy and a peak force of 3.77 kN were achieved, indicating superior energy dissipation and damage resistance. These improvements are attributed to enhanced interfacial bonding and efficient load transfer facilitated by uniformly dispersed rGO. The developed composites show strong potential for automotive interior components, lightweight structural panels, protective casings, and sustainable Engineering applications requiring improved tensile and impact performance.
