Abstract

had been investigated for hard panel application. The raw material used were unsaturated polyester resin, cotton fiber and wire mesh. This research was aimed to investigate the effect of cotton fabric on the mechanical and physicaJ properties in hybrid laminated composite for the hard panel. In addition, this research also sought to identify the best layer and arrangement in hard panel and to identify the failure mode behavior of hybrid laminate composite upon mechanical and physical testing in different layer and arrangement of reinforcement. Eleven samples of hybrid laminated composite were fabricated according to the number of layer, arrangement and ASTM standard. Based on the mechanical and physical testing on the hybrid laminated composite, it has found that the laminated composite SN 7 give the optimal mechanical and physical properties compared to the other. SN 7 is a laminate with total ten layer of cotton fiber where five layer of cotton at the top and five layers at the bottom of the wire mesh give the best value for each testing. For tensile strength, SN 7 gave 29.354 MPa, flexural strength with 61.08 MPa, hardness with 84.2 and bolt push with 4452.66 N. It was concluding that SN 7 was better than other sample.
