Abstract
Currently, natural materials such as corn silk have not received much attention in the industry, especially their use as materials. Nonetheless, in recent years, researchers have begun to turn their attention to more environmentally friendly composite materials. Therefore, it is important to carry out an analysis of the potential use of corn fiber in making composites, especially when combined with vinyl-ester and epoxy matrices. Thisresearch aimsto calculate the maximum shear stress and maximum shear strain of corn fiber composites with vinyl-ester and epoxy matrices by carrying out torsion tests on several different volume fractions. This research method is a quantitative method where this research will use volume fractions of 25%, 30%, 35% and 40% corn fiber with a vinyl-ester and epoxy matrix. The composite was molded using a standard E143 mold then dried for 2 days, then a torsion testing process was carried out. The test results showed that the epoxy resin and vinyl-ester composite experienced a decrease in shear stress and maximum shear strain at a fiber volume fraction of 40% and the maximum shear stress and shear strain are at 35% fiber volume fraction. The maximum shear stress and shear strain in epoxy resin are 25.97 MPa and 0.81, while the maximum shear stress and shear strain in vinyl-ester resin are 30.24 and 0.94. Keywords: Composite, corn fiber, vinyl-ester, epoxy, torsion test Sekarang ini, material alami seperti rambut jagung belum mendapatkan banyak perhatian di industri, terutama penggunaannya sebagai material. Meskipun demikian, dalam beberapa tahun terakhir, para peneliti telah mulai mengarahkan perhatian mereka ke material komposit yang lebih ramah lingkungan. Oleh karena itu, penting untuk melakukan analisis mengenai potensi kegunaan serat jagung dalam pembuatan komposit, khususnya ketika digabungkan dengan matriks vinyl-ester dan epoxy. Penelitian ini bertujuan untuk menghitung tegangan geser maksimum, regangan geser maksimum komposit serat jagung dengan matriks vinyl-ester dan epoxy dengan melakukan uji puntir pada beberapa fraksi volume yang berbeda. Metode penelitian kali ini adalah metode kuantitatif di mana penelitian ini akan menggunakan fraksi volume 25%, 30%, 35%, dan 40% serat jagung dengan matriks vinyl-ester dan epoxy. Komposit dicetak dengan cetakan standard E-143 lalu dikeringkan selama 2 hari, kemudian dilakukan proses pengujian puntir. Hasil pengujian menunjukkan bahwa komposit resin epoxy dan vinyl-ester mengalami penurunan tegangan geser dan regangan geser maksimum pada fraksi volume serat 40% dan tegangan geser dan regangan geser maksimum ada pada fraksi volume serat 35%. Tegangan geser dan regangan geser maksimum pada resin epoxy adalah 25.97 MPa dan 0.81, sedangkan tegangan geser dan regangan geser maksimum pada resin vinyl-ester adalah 30.24 dan 0.94. Kata Kunci: Komposit, serat jagung, vinyl-ester, epoxy, uji puntir
