Product development of a car bumper beam is a critical activity since it is important in order to reduce an impact during a car collision. Currently, most of the production of the bumper beam is manufactured using existing materials such as aluminium. This material has the potential to be replaced with a more environmentally friendly material, which is the bio-reinforced polymer matrix composites. However, engineers are facing problems during the selection of materials selection to form these composites due to properties variations and muti-combinations of materials. In order to overcome this problem, Quality Function Deployment (QFD), Analytic Hierarchy Process (AHP), and Finite Element Analysis (FEA) have been combined to perform the material selection. The objective of this paper is to obtain the best bio-reinforced polymer matrix composites for the application of a car bumper beam. The result has indicated that the flax reinforced polypropylene (Flax+PP) has been the best material obtaining the best normalized score of 0.387, followed by kenaf reinforced polypropylene (0.335), and sisal reinforced polypropylene (0.122).
