Study On the Flexural and Impact Properties of Short Okra Natural Fiber Reinforced Epoxy Matrix Composites

Abstract

The okra natural fiber reinforced epoxy matrix composites were prepared byhand-lay-up. The weight fractions of okra fiber are (1, 3, 6, 9, and 12% by weightwt). The flexural properties and impact resistance of composites were determinedby the flexural and impact tests. The maximum modulus of elasticity is (844.93MPa) at the weight fraction of (12 % wt) of okra fiber, comparison with (91.25MPa) for virgin epoxy material. The maximum impact energy is (0.75 J) at theweight fraction of I(12 % wt) of okra fiber, comparison with (0.05 J) for virginepoxy material.
