Finite Element Analysis of Internal Door Panel of a Car by Cons idering Bamboo Fiber Reinforced Epoxy Composite

Eskezia E, Abera A and Daniel Tilahun

In this paper work the dynamic structural Finite Element Analysis of internal door panel of a vehicle by considering bamboo fiber reinforced epoxy composite (BFREC) materials was conducted. The objective of the paper is to develop a suitable model of internal door panel for Toyota DX car, to conduct a transient dynamic structural analysis (stress and displacement analysis) of internal door panel by finite element method, to compare the performance of BFREC material with previously recommended materials of internal door panel. The door panel of Toyota Corolla DX model vehicle was used to develop the geometric model of the internal door panel by CATIA V5 R20 modeling software. This 3-D geometric model was imported to using ANSYS Workbench 15.0. The transient dynamic structural FEA was done after assigning loading and boundary conditions. The applied load considered for this analysis is the self-inertial weight of the panel due to the acceleration field produced while the door is closing. The equivalent stress and the displacement are noted and investigated to compare with the literatures revised. The result shows that, bamboo fiber reinforced epoxy composite panel has the smallest mass and equivalent stress values, as compared with the lignocellulosic composite and polypropylene one. Based on these realities, it is recommended that bamboo fiber reinforced with epoxy composite materials are suitable for internal structural automotive panel applications.
