In this research, the combination of oil palm fiber and glass fiber as reinforcing fibers in polyester composites was evaluated. The mechanical and physical properties of oil palm empty fruit bunch/glass hybrid reinforced polyester composites were studied. Hybrid laminate composites with different weight ratios (w/w) of chopped strand mat (CSM) glass fibers: oil palm empty fruit bunch fiber (EFB) 3: 7, 5: 5, 7: 3, 9: 1 were prepared. The hybrid effect of glass and EFB fibers on the tensile, flexural, impact, and hardness of the composites were investigated. Water absorption and thickness swelling were also conducted. In general the hybrid composites exhibited good properties compared to the EFB/polyester composites.
