Evaluation of mechanical properties on kenaf fiber reinforced granite nano filler particulates hybrid polymer composite

Abstract

Natural fibers are prime focus as a potential alternate material instead of synthetic fiber to making the composite material for automobile applications. In this work, kenaf fiber was selected as reinforcement material, granite powder act as a filler material and the epoxy polymer used as matrix material to fabricate the composite laminates by hand layup method with varying the fiber and filler weight ratio of three different samples. To analyses the mechanical properties of tensile, flexural strength, impact energy and hardness of hybrid composite. The results are revealed when the addition of kenaf fiber can improve the tensile and flexural strength are 35.16 MP and 39.54 MPa respectively. In the sudden force experiment was given maximum impact energy of 15 J for sample C, also the hardness number was varied in maximum of sample B is 54. The surface morphology of hybrid composite was conducted through microscopic analysis for all the fabricated samples before conducting the mechanical test.
