The purpose of this study is to compare the tensile strength between additional polystyrene into
coconut meat husk reinforced fiber composite. Composite were produced by using hand layup
technique. It is seen that with the additional of polystyrene into the coconut meat husk reinforced
polyester composites showed the increment tensile strength value compared to the non added
polystyrene which indicates that effective stress transfer between the fiber, matrix and
polystyrene .
