Abstract

Industri otomotif telah menanggapi isu global tentang krisis energi dengan banyak memproduksi kendaraan yang hemat bahan bakar dan memiliki berat yang ringan. Body kendaraan merupakan komponen yang paling mudah dimodifikasi untuk mengurangi berat kendaraan, dan material yang sesuai yaitu dengan komposit berpenguat serat alam. Serat alam merupakan alternatif filler komposit untuk berbagai komposit polimer karena keunggulannya dibanding serat sintetis. Di antara berbagai jenis serat alam, sisal merupakan salah satu tanaman yang paling banyak digunakan. Serat sisal merupakan penguat yang menjanjikan untuk digunakan sebagai komposit karena harganya yang murah, densitasnya rendah, kekuatan spesifik dan modulusnya tinggi, tanpa resiko kesehatan serta tersedia melimpah dan merupakan bahan alam terbarukan. Material yang diteliti menggunakan komposisi berupa epoxy resin dan serat sisal. Spesimen uji tarik dibuat sesuai dimensi ASTM D3039-105 dengan variasi struktur serat sisal chopped, continue, woven dan masing-masing struktur divariasikan dengan fraksi volume serat sisal 40%,50%,60% Komposit dibuat dengan komposisi yang sudah ditentukan, dan dituang dalam cetakan, dibiarkan mengeras dengan temperatur kamar selama 24 jam, spesimen yang sudah jadi dilakukan uji tarik untuk mengetahui sifat mekanik yang terjadi pada komposit. "=============================================================================================" The automotive industry has responded to the global issues of energy crisis by producing more fuel-efficient and a light weighted vehicles. The vehicle body is the most easily modified component to reduce the weight of vehicles, and the corresponding material composite fiber is by nature. Natural fiber composites are an alternative filler for various polymer composite because of its superiority compared to synthetic fibers. Among the various types of natural fibers, sisal plant is one of the most widely used fiber. Sisal fiber amplifier is promising to be used as composite because the price is cheap, has low density, with high specific strength and modulus, without health risks and is available in abundance and is a renewable natural material. The material studied using the composition is in the form of epoxy resin and sisal fibers. Tensile test specimens made according to ASTM D3039-105 dimension by varying the structure of sisal fiber chopped, continue, woven and each structure varied with sisal fiber volume fraction 40%, 50%, 60% composites made with a predetermined composition, and poured in mold, allowed to hardened at room temperature for 24 hours, the finished specimens were tested to determine the tensile mechanical properties that occur in the composite. The research result obtained that the continue fiber structure generated the highest tensile stress values, followed by the woven structure and the smallest tensile stress value is
