Comparison of variations of bamboo fiber reinforced epoxy composite with adding powder material for bulletproof application

Mechanical Engineering

This study aims to analyze the feasibility of applying bamboo composite material for bulletproof needs using the 70 °C chemical extraction method on bamboo fibers. Composites are made by adding aluminum powder, silicon dioxide powder, fluorocarbon powder which have different variations. From the results obtained using the chemical extraction method at 70 °C on bamboo, it shows that the strength of apus bamboo is 9.68 N/mm2 (90 minutes), Japan 7.995 N/mm2 (120 minutes) and Yellow 8.15 N/mm2 (60 minutes). While the results of the tensile test on the composite material showed 20.375 N/mm2 (3.2), 1.13% strain (2.3) and 18.98 N/mm2 (3.2) elasticity. The impact strength is 3.37 Joules (2.1) and the ductility is 1.87 Joules/mm2 (3.3). The bending test stress showed 92.61 MPa (3.2), 5.32% strain (1.3) and 6755.67 MPa (3.3) bending elasticity. Vicker Hardness Test 2.47052 x 10-07 gf/µm2 (1.3) and water absorption 0.02% (3.2). From several ballistic test results using simulations using ansys 2018 R1 shows that the highest maximum total deformation is found in composite types of Japanese bamboo fiber 4.4461 mm, while the highest equivalent stress is in yellow bamboo 97.596 MPa, and the highest equivalent stress is in yellow bamboo 97.596 MPa, and the main stress was found in yellow bamboo. type of composite with a maximum of 102.39 MPa, while the maximum directional velocity of 258.48 mm/s is found in apus bamboo.
