Hybrid composite were fabricated with ± 45 o and ±90 o oriented reinforcement as E glass fiber with Hematite ore (Fe 2 O 3 ) filler material and Polyester resin matrix. The filler content was varied as 6wt%,8 wt% and 10 wt%. The laminates were prepared by hand layup technique, cured at ambient temperature, laminates are peeled according to ASTM standards and the experiments were conducted to determine tensile strength, impact strength and hardness. The result showed that Hematite filled composite better than unfilled composite. The ±90 o oriented composite exhibits better result compared to ±45 o oriented composite. The 6wt% hematite filled glass/polyester has shown excellent to the other studied composite both in ± 45 o and ±90 o oriented composite. Keywords: Composites; Impact Strength; FRPC; Hematite ore.
