Abstract
Bulletproof vests are made to protect the human body from bullets that cause injuries or other dangerous conditions. Research on composite materials as bulletproof vests continues to develop to get bulletproof vests that are more flexible and lighter. Carbon Fiber Reinforced Polymers (CFRP) composites are widely developed as soft body armor materials because they have high strength, good impact strength and light weight. In this study, an analysis of the soft body armor bullet-proof vest made of carbon fiber reinforced plastic was carried out using the finite element analysis (FEA) method. The simulation was carried out in accordance with the national institute of justice standard 0101.06 U.S department of justice where the initial velocity of the bullet was 373 m/s for the soft body armor type by varying the thickness of the bulletproof vest until the optimal thickness was obtained. The simulation results show that the thicker a dinner vest, the better it will absorb impact energy, this is due to the nature of carbon fiber which is able to distribute stress evenly.
