The bulletproof material serves to withstand the bullet attack by holding back the penetration and impact produced by the bullet. In its development, carbon fiber composite has been popular in bulletproof material as it has high modulus strength, good flexibility, and low in density. The simulations of ballistic impact with Abaqus/Explicit were conducted to give the numerical result of the carbon fiber's mechanical behavior and give the penetration and perforation phenomena of the bullet type 1 with different amounts of plies were used. The carbon fiber/epoxy was modeled with hashin damage, and the bullet was modeled with Johnson-Cook damage model. Based on the simulation results, 14 plies of Carbon Fiber/Epoxy with a thickness of 4.2 mm can withstand bullet penetration. As a result, 14 plies carbon fiber/epoxy absorb 130 Joules of kinetic energy and transmit 42.9 Joules of energy. The damage that occurs in carbon fiber/epoxy is in the form of radial fracture, and the bullet shape changes in a round shape. © 2023 Author(s).
