Composite bulletproof vest reinforced rubberized coir

Abstract

Bulletproof vests are safety protective equipment commonly used by the police, military, security agencies and people who are at risk of being shot targets. This study aims to create a bullet rate-resisting composite material from rubberized coir (sebutret) as a substitute for Kevlar with a cheaper and more economical price. In this study, the specimen used was a combination of a resin composite reinforced with coconut fiber and rubber latex. Then for data collection using the Brinell hardness test, the Charpy method impact test and the ballistic firing test. Then analyze the data from the results of the hardness test, impact test and firing test. Based on the results of the hardness test, it has the highest average of 22.86 BHN at a mixed variation of 40%, the result of the impact test has the highest verage of 0.087 J/mm2. So it can be concluded that the 40% mixture variation is best used for making bulletproof vest panels. The results of the firing test showed that the 40% mixture variation of 1-ply panels was able to withstand the rate of bullet rotation because the mixture of resin and coconut fiber was stronger and denser
