Abstract

Cellulosic (sisal, bamboo, coir, etc.) fiber reinforced polymer composites have played a dominant role for long time in a variety of applications (automobile, structural, etc.). Cellulosic fibers are bio-degradable, are of low cost and have high strength to weight ratio. In the present work, mechanical properties (tensile, flexural, compression and hardness) are tested for sisal/coir; sisal/hemp and sisal/flax fibers reinforced epoxy hybrid composites according to ASTM standard. Traditional hand-lay-up method was used to prepare the hybrid composite. Lignin, pectin and dirt were removed by NaOH treatment of fibers. The experimental results reveal that the sisal/hemp fiber reinforced hybrid composites exhibit more tensile and flexural strength and sisal/coir fiber reinforced hybrid composites exhibit more compression strength and hardness.
