|Abstract:||The main goal of this study is to investigate the impact analysis of sisal fiber reinforced epoxy resin composite material for automotive applications using Abaqus/CEA 6.13 software based on ASTM D-7136 standard. For this simulation a 4 unidirectional sisal/epoxy composite lamina te with overall thickness of 2.16 mm was used, and 0.5kg, 1kg, 2kg and 3kg of impactor mass with 1 m/s, 2 m/s and 3 m/s of velocities were used in order to deal their effects on the composite laminate. Generally, in order to get the Abaqus/Explicit software in put data’s, first the sisal fiber was extracted manually from the sisal plants and treated with 8% of NaOH. Then the testing specimens was manufactured using volume fraction of 60% matrix and 40% of sisal fibers using vacuum bagging assisted hand lay-up technique (VBAHT) , and finally the tensile, compression and in-plane shear test was conducted based on their ASTM standards. The impact simula tio n results showed that when the impactor mass and velocity increases, the contact forces of the composite plate was increase up to 1kg of the impactor with 3m/s. Apart from that, the reaction forces of the composite plate was decreased and perforation of the plate was takes place for 2kg and 3kg of impactor mass. From all force-time history graph, the highest reaction force of 656.69 N occurred at 1kg of impactor for 3m/s. Furthermore it is found that the sisal fiber reinforced epoxy resin composite material has a good energy absorption capacity (up to 4.5 J) in the transverse direction and can have a potential to be used for different automotive application.|
