Abstract
Natural fibers are emerging as low cost, lightweight and apparently environmentally superior alternatives to glass fibers in composites which are used in the aerospace, transportation and construction industries. The extensive research and development of new and improved materials such as composites is going on. Composite materials used for structural purposes often have low densities, resulting in high stiffness to weight and high strength to weight ratios when compared to traditional engineering materials. Composites are of low cost, bio degradable and easily can recyclable through thermal methods. In addition, to the high fatigue strength to weight ratio and fatigue damage tolerance of many composites also makes them an attractive option. The light-weight natural fiber composites improve fuel efficiency and reduce emissions in the use phase of the component, especially in auto applications. The main goal of this thesis is to develop and characterize the performance of bamboo and sisal fiber reinforced polyester hybrid composite (BSFRHC) with different fiber orientation of sisal and unidirectional (UD) bamboo fiber for interior automotive body application. Manual method of sisal fiber extraction from Dessie town and bamboo fiber extraction from Ethiopian highland bamboo ‘Yushania Alpina’ species was undertaken. A 5% sodium hydroxide was used for further lignin, hemicellulose and other fiber remnants removal for the improvement of bond & interfacial shear strength of the bamboo and sisal fiber for each. Next, BSFRHC was fabricated with 20 % total fiber volume fraction. Of this total fiber volume, the composite is fabricated in 3:1 bamboo to sisal fiber ratio using hand lay-up technique. Then tensile, compressive, impact and flexural tests were carried out. Unidirectional 900 fiber orientation was found to have a higher tensile and flexural strength whereas unidirectional 900 and bidirectional (00/900)fiber orientation nearly have the same value of tensile strength, whereas bidirectional (00/900) was found to be having higher flexural strength than unidirectional 900 fiber orientation. Finite element analysis on internal door panel made of BSFRHC was done in ANSYS Software using impactor. Furthermore, it is found that the bamboo and sisal fiber reinforced hybrid composite in unidirectional 00 has a potential to be used for automotive interior door panel application.
