ENHANCED MECHANICAL PROPERTIES OF NATURAL FIBER BAMBOO/ PINEAPPLE LEAF/ COCONUT HUSK REINFORCED COMPOSITES FOR APPLICATION IN BIO-BOARD

Abstract

In this work, an experimental study of the behaviour of bamboo fiber/pineapple leaves/coconut
fiber reinforced with epoxy resin is presented. The properties of the material were tested using a universal
testing machine and crack surface structure through scanning optical and electron microscopy with the material
combined with epoxy resin to become a hybrid composite material to determine the best characteristics of the
tensile test properties treated with 6%. NaOH on every fiber. The results showed that the fiber mixture between
bamboo/pineapple leaves and coconut fiber showed an increased tensile strength of 304.7 MPa compared to
bamboo/pineapple leaves and 293.6 MPa compared to pineapple/coconut fiber leaves 268.2 MPa and the
lowest Polyester was 109 MPa. The morphological appearance of each combined fiber brings diffusion of the
polymer matrix to the porous fiber surface where the polymer matrix is compacted in a strong bond, causing
the presence of bamboo fibers that have a high cellulose content which can replace apple failure. Pine leaves
and coconut fiber and make hybrid composites not only as a strong material but also biodegradable.
