Experimental Study on Mechanical Properties of Laminated Bamboo Strip/Alumina Particulate/ Epoxy Composite

Abstract

Composites consist of natural fiber materials that offer attractive strength equivalent to conventional materials. However, the defect of bamboo is its hydrophilic character, severed with some properties which affect the performance of fibers. Synthetic fiber composite becomes expensive, non-biodegradable, and environmentally unfriendly, to address such issues and the necessity of composite in the automobile, aerospace, and construction industries. This paper is present an experimental studies on laminated bamboo strip fiber reinforced with alumina particulate to polymer composite. In recent years, Natural fiber composites have gained significant popularity as structural materials due to their stiffness and high strength with a low cost, as well as their light weight, short growing cycle, biodegradability, eco-friendliness, and high availability. For physical and mechanical characterizations, the specimen is prepared using the hand lay-up manufacturing processing techniques. Mild steel mold with dimensions of 320x260x50mm. The composite plate constitutes weight loading of bamboo/epoxy compositions is 25%:70%, 20%:70%, and 15%:70% with 5wt%, 10wt%, and 15%wt of Al2O3. Epoxy (LY556) and hardener (HY951) were used to mix in the ration 100:10 for curing bamboo composite with the reinforcement orientation on (00 /900&±450 ). The laminated composite ply stacking sequence on the [0/900 ]S and [±450 ]S. During this work, conduct mechanical property tests under ASTM standards, such as tensile, compression, flexural strength, hardness, and impact strength and water absorption. The greatest value for tensile strength is 86.7Mpa, flexural strength is 247.5Mpa, hardness is 207Hv and impact 6.984kJ/m of composite obtained at 5wt%, 15wt% and 10wt%alumina, respectively, and FTIR is intermolecular interaction between fibers and resin of materials. The goal of the study is to improve the mechanical properties of the bamboo composite that has been developed
