This thesis work presents the structural Finite Element Analysis of internal door panel of a vehicle by considering bamboo fiber reinforced epoxy composite materials. 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 3D geometric model was imported to using ANSYS Workbench 15.0. The transient dynamic structural FEA was done after assigning displacement, load 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 of this analysis shows that, the equivalent stress of bamboo fiber reinforced epoxy composite panel has the smaller value, as compared with the lignocellulosic composite and polypropylene one. The displacements of bamboo fiber reinforced epoxy composite internal door panel obtained by FEA are smaller by 34% and 50% than that of the lignocellulosic composite materials and the polypropylene panel respectively. In addition, the mass of this newly modeled panel is reduced by 6% and 8% than that of the panels of the above mentioned materials respectively. Based on these realities, it is recommended that bamboo fiber reinforced with epoxy composite materials are suitable for internal structural automotive panel applications.
