The Effect of Matrix on the Mechanical Properties Fiber Reinforcement Plastic Wall Rails

Abstract

Along with the development of science and technology today, one of the ways that can be done to find a material with better properties is to combine two or more substances with different properties or phase. This kind of material is called composite material. In this study, a composite material made with E-Glass fibers with a corresponding number of layers used in the process is an artificial product INKA train wall. Composites made using hand lay up with a variety of types of matrix epoxy, polyester, bisphenol, and repoxy. Mechanical properties observed that the tensile strength and bending strength which refers to standard ASTM D638 and ASTM D790. The results of tensile testing showed repoxy matrix has the highest strength of 181.67 MPa with0.02872 strain mm, while the polyester matrix having the lowest strength of 154 MPa and a strain of 0.02184 mm.
