Abstract

Nowadays, most of scientist and manufacturer are looking for lightweight materials to reduce fuel consumption and gas emission to surrounding from vehicles. In order to solve the problems, the lightweight of alternative material from natural fiber are greatly treasured by scientist and manufacturer. This is because natural fibres are lightweight material, cheaper and the sources mostly available. Therefore, the research is about material selection of natural fibre and matrix of automotive body panel for FML. The objective for this project is to select best material of natural fiber and matrix for FML. The method involved in material selection is CES Edupack software and Pugh method analysis. There are has five stage of CES Edupack which is problem statement, objective function, objective constraint, screening, and ranking of the materials. In order to eliminate material that not satisfies in this project, the material are sort out according to material limitation stage and attribution of properties against another properties. The limitation stage are applied for natural fibre material selection which is non-toxic material, durability of water, and biodegradable material while no limitation stage for matrix. Besides that, the constraints involve in scanning and ranking step in CES Edupack software 2013 is attribution of Young’s modulus, yield strength, density, price, and performance index line in order to determine the stiffness, strength, lightweight at reasonable cost. The result proposed by CES Edupack software for natural fibre is kenaf fiber, jute fiber, and ramie fiber. While, material candidates for matrix is PP (homopolymer, high flow), PP (homopolymer, low flow), PP (homopolymer, darified/nudeated), PS (heat resistant), and PLA (unfilled). In order to get best material, the candidate materials for natural fiber and matrix are compared by using Pugh method for justification. The materials are compared by using symbol indicator based on objective function to the project and current material as the datum.The datum for natural fiber is steel while the datum for matrix is epoxy. Therefore, the analysis shows that kenaf fibre and PP (homopolymer, darified/nudeated) are selected as best candidates for natural fiber reinforcement FML and fulfil the objective constraint in this study which is lightweight material, minimize cost, and maximize the performance.
