Abstract

Many researches have been conducted on natural fibers and results show that it is suitable to replace synthetic fiber. In this experiment, banana fiber has been selected to study the possibility of this material as reinforcement material in composite. By using banana fiber as a material to reinforced composite, we can fully utilize the waste rather than being abandoned and dispose. The composite are prepared by using pure polyester with 1% wt fiber loading, 2% wt fiber loading and 3% wt fiber loading reinforced polyester. Two tests were conducted, which is 3 point bending and tensile test. From this experiment, flexural stress and tensile stress of banana fiber reinforced composite are decreased as fiber loading increased. The flexural stress of pure polyester is 55.625MPa and decreased to 34.805MPa when 3% wt fiber loading used. Meanwhile, tensile stress of pure polyester is 19.86MPa and when 3% fiber loading used to reinforce polyester composite, the value of tensile stress reduce to 11.602MPa. Although the results showed in this experiment are not encouraging, but other research and study have proved that this material has a potential to apply in industry. The reasons that lead to these problems are discussed in chapter 4 in this report.
