Tensile Properties Of Woven Kenaf Fiber Reinforced Polypropylene Hybrid Aluminium-Composite

Concern on environmental impact of emission from the automobile and the uncertainties in fuel price has led to the development of lighter materials. Hybrid metal-composite is a sandwich structure which is lighter than its constituent monolithic metal. In this study, hybrid aluminium-composite (HAC) was fabricated using plain weave woven kenaf fiber reinforced polypropylene matrix composite sandwiched in between aluminium 6061-O using hot compression method. Tensile test was conducted on the HAC with two different fiber loading and fiber orientation. The fiber loading were with 1 mm pitch (X-type) and 5 mm pitch (Y-type) and the orientation were 0° and 45°. The result shows that tensile strength had been increased with the increment of fiber loading, where X-type tensile strength is higher than Y-type. Meanwhile, 45° fiber orientation gives higher tensile strength compared to 0°. The images of the fracture type experienced by the HAC after the tensile test was also observed
