In present scenario, natural fiber reinforced composites have raised more attention for the growth of biodegradable material and are somewhat replacing presently used artificial fibers. Natural fibers able to replace the synthetic fibers that it has the eminent benefits of like low density, small manufacturing cost, its availability, ease of manufacture, low development energy, non-abrasive, worthy acoustic property, biodegradability, reasonable mechanical strength, renewability. Composite were made-up by hand lay-up method with the bidirectional natural fibers and epoxy resin in a mould and cured under gradual pressure. In this research paper mechanical behavior such as tensile, impact, indentation capacity and water absorption test of E-Glass and kenaf/flax mat reinforced hybrid composite materials (GKFHC )studied. The purpose of this work to investigate the mechanical characterization of the hybrid composite material. Sample was prepared and tested accordance to the ASTM standards.
