Composite, Fiberglass, Ceiba PentandraAbstract
This study investigates the mechanical strength of composites made from Ceiba pentandra fiber and fiberglass using the Vacuum Assisted Resin Infusion (VARI) method for Kopasgat knee pad applications. Impact and bending tests were conducted on three specimen types: pure fiberglass, 70% fiberglass–30% Ceiba, and 50%–50% mixtures. Results showed pure fiberglass had the highest impact energy (27.36 J), while all composites absorbed more energy than the original knee pad material (6.96 J). Adding Ceiba fibers improved flexibility and reduced weight. Overall, the Ceiba–fiberglass composite is suitable as a lightweight, strong, and comfortable alternative for knee pads.
