Natural fiber reinforced polymer composites plays important role in the fuel efficiency and emission gas regulation of passenger cars. The best way to increase the fuel efficiency with out sacrificing safety is to employ fiber reinforce composites materials in the body of the cars so that weight reduction can be achieved. Designing the bumper with the focus on improvement aspects is very important in the automotive industry. The goals are to increase the performance of the bumper and also to find the solution to reduce the cost of bumper hence able to reduce the production cost. The latest thermo plastic developments have resulted in higher material properties and more possibilities in the design of bumper beams. However the use of steel, Aluminum, Glass mat thermoplastics (GMT), sheet metal components (SMC) Bumpers becomes at higher cost than long fiber reinforced thermoplastics. This research is focused on partially eco- friendly hybrid long fiber reinforced thermo plastics with natural kenaf fiber to enhance the desired mechanical properties for car bumper beams as automotive structural components. A specimen without any modifier is tested and compared with a typical bumper beam material called LFRT. the results indicate that some mechanical properties such as tensile strength , young's modulus, flexural strength an flexural modulus are similar to LFRT , the new material also must improve the ability to absorb more impact load and increase the protection of the front car component. © EuroJournals Publishing, Inc. 2011.
