Abstract

Body armor merupakan perlengkapan perlindungan diri dari peluru senjata api. Body armor terdiri dari lapisan keras (hard plate) dan lapisan lunak (soft plate) lapisan keras berfungsi untuk menahan penetrasi dari peluru sementara lapisan lunak berfungsi untuk menyerap energi impact akibat tumbukan. Panel body armor umumnya terbuat dari logam, keramik atau komposit dengan massa yang cukup berat. Panel keramik memiliki keunggulan dari sisi kekerasan namun kurang baik dalam menyerap energi impact. Body armor komposit memiliki strength-to-weight ratio yang tinggi dan dapat melindungi dengan baik. Serat alam memiliki potensi dari segi budidaya, pengolahan, serta pemanfaatan produknya. Banyak penelitian terkait pemanfaatan serat alam sebagai penguat komposit panel anti peluru telah dilakukan. Serat alam memiliki kekuatan yang baik, ramah lingkungan, serta harga yang terjangkau. serat alam yang banyak dimanfaatkan di dunia tekstil adalah serat dari tanaman rami (Bohmeria nivea). Penelitian ini membahas ketahanan penetrasi dan serapan energi komposit serat rami dan SiC sebagai panel anti peluru melalui pemodelan dan simulasi numerik. Simulasi uji balistik dilakukan mengacu pada NIJ 0101.06 level IV. Simulasi dilakukan terhadap panel komposit rami-epoxy, panel rami-epoxy – SiC dengan lokasi tumbukan tepat di tengah keping SiC (panel A), di antara dua keping SiC (panel B), dan di antara tiga keping SiC (panel C). Hasilnya didapatkan konfigurasi panel yang memenuhi kirteria NIJ 0101.06 berupa rami-epoxy 74-layer dengan ketebalan 76,22 mm dan konfigurasi panel rami-epoxy – SiC 33-layer dengan ketebalan total 37,99 mm. ================================================================================================ Body armor is self-protection equipment from firearm bullets. Body armor consists of two types of layers, namely a hard layer and a soft layer, the hard layer serves to withstand the penetration of bullets while the soft layer serves to absorb impact energy due to collisions. Body armor panels are generally made of metal, ceramic, or composite. Metal body armor has a good protection power but has a heavy mass. Ceramic panels have advantages in terms of hardness but are not good at absorbing impact energy. Composite body armor has a high strength-to-weight ratio and provides excellent protection. Natural fiber has good potential in terms of cultivation, processing, and utilization of its products. Many studies related to the use of natural fibers as reinforcement for bullet-proof panel composites have been carried out. Natural fibers are known to have good strength, environmentally friendly, and relatively affordable prices. One of the natural fibers that is widely used in the textile world is fiber from the hemp plant (Boehmeria nivea). This study discusses the penetration resistance and energy absorption of flax fiber composites and SiC as bulletproof panels through numerical modeling and simulation. The ballistic test simulation was carried out according to NIJ 0101.06 level IV. Simulations were carried out on hemp-epoxy composite panels, rami-epoxy-SiC panels with the collision location right in the middle of the SiC chips (panel A), between two SiC chips (panel B), and between three SiC chips (panel C). The result is a panel configuration that meets the criteria of NIJ 0101.06 consist of 74-layer rami-epoxy with a thickness of 76.22 mm and 33-layer rami-epoxy – SiC panel configuration with a total thickness of 37.99 mm.
