Experimental Studies on Hybrid Epoxy Matrix Composite
Jute and sisal fibers are the most potential natural fibers to produce composites currently used for industrial
structures and as bio-materials. In the present investigation jute and sisal fibrous mat is reinforced in an epoxy matrix by
manual layup technique to produce a hybrid composite. The composite is tested for tensile strength and impact strength.
The fabricated composite with [0 0 /0 0 ] orientation of fibers exhibited higher tensile strength than that of composite with
[0 0 /90 0 ] orientation of fibers.The energy absorbing capacity of later was high than the former type of composite. The
scanning electron microscopy image of thefractured specimensrevealed that de-bonding between fiber matrix interface and
void nucleation growth are the major factors influencing failure of the material.
