Abstract

Body armor menggunakan bahan material logam yang memiliki kekuatan tinggi, namun bobot materialnya berat. Dalam pengembangan body armor, material komposit menjadi material pilihan karena sifatnya yang kuat dan ringan. Material komposit terdiri dari dua bahan penyusun yaitu matriks berupa epoksi dan penguat berupa serat karbon. Komposit serat karbon dengan kekuatannya yang tinggi, dapat ditingkatkan dengan penambahan penguat partikel berupa silicon carbide (SiC). Penelitian ini bertujuan menganalisis pengaruh partikel silicon carbide terhadap morfologi dan sifat mekanik komposit epoksi berpenguat serat karbon sebagai aplikasi material anti peluru (body armor). Variasi komposisi partikel SiC yang digunakan adalah 0, 4, 8, 12, dan 16 wt% dengan pengujian yang dilakukan yaitu SEM, FTIR, kekuatan tarik, kekerasan, densitas, dan tembak. Hasil pengujian yang didapat bahwa partikel SiC mempengaruhi morfologi dan meningkatkan sifat mekanik, dimana hasil optimum terjadi pada komposisi 12 wt% SiC dengan nilai kekuatan tarik 336,87 MPa, modulus Young 3,48 GPa, elongasi 16,09 %, kekerasan 81 HD, dan densitas 1,31 gr/cm3, serta memenuhi standar uji tembak NIJ level IIA.

Body armor uses metal materials that have high strength, but the weight of the material is heavy. In the development of body armor, composite materials are the material of choice because of their strong and light properties. The composite material consists of two constituent materials, namely the matrix in the form of epoxy and the reinforcement in the form of carbon fiber. Carbon fiber composites with high strength can be improved by adding particle reinforcement in the form of silicon carbide (SiC). This study aims to analyze the effect of silicon carbide particles on the morphology and mechanical properties of carbon fiber reinforced epoxy composites as a body armor application. Composition of SiC particles were 0, 4, 8, 12, and 16 wt% with the tests carried out namely SEM, FTIR, tensile strength, hardness, density, and firing. The results showed that SiC particles affect morphology and improve mechanical properties. The optimum results occur in the composition of 12 wt% SiC with a tensile strength value of 336.87 MPa, Young's modulus 3.48 GPa, elongation 16.09%, hardness 81 HD and a density of 1.31 gr/cm3. The material meets the NIJ level IIA firing test standards.
