Abstract

In recent years natural fiber appear to be the outstanding materials which come as the viable and abundant substitute for the expensive and non-renewable synthetic fiber. Among the materials used for the fabrication of automotive hood such as Aluminum Alloy, Magnesium Alloy, Carbon fiber and natural fiber is Kenaf Fiber reinforced Polypropylene. This project overall is discussed about the potential of natural fiber composite in automotive industry to develop the automotive hood. The main objective in this project is to determine the appropriate material to be used in fabricating automotive hood. From design a hood car by using CATIA CAD Software and conduct the design analysis using SolidWorks Simulation software. Redesign the automotive hood is done in the CATIA CAD. SolidWorks Simulationxpress software was used for Finite Element Analysis. For the comparison, the mass, stress, displacement and factor of safety is used for materials selection. From the results, the data were through the scoring process and discussed in detail based on the result from the Finite Element Analysis. Based on analysis of data obtained as a result of the test, the Magnesium Alloy is the best material for fabricated automotive hood. However, Kenaf fiber reinforced with polypropylene has the potential to replace existing materials used in the manufacture of car hood. For the recommendation in the future researcher is to test using Dynamic analysis then, an actual impact testing on the fabricated automotive hood should be conduct to obtain an experimental result. The experimental result could be compared with the analysis that has been made before and also can determine energy absorption of the materials used.
