IMPACT ANALYSIS ON COMPOSITE HELMET BY USING FRC AND GLASS FIBER BY USING ANSYS Amal Thomas [1], Dr.P.Suresh [2], J. Anish Jafrin Thilak [3] N.Subramani [4] PG Scholars, Karpagam College of Engineering, Coimbatore, India [1] Dean and Professor, Karpagam College of Engineering, Coimbatore, India [2] Assistant Professor, Karpagam College of Engineering, Coimbatore, India [3, 4] -------------------------------------------------------------------------------------------------------------------------------- -------------------------ABSTRACT In this work impact analysis is carried out in the Composite Helmet by Using FRC and Glass Fiber. In this recent world the fiber strengthened composite materials are synthesized using glass fiber as reinforcements together with matrix, which have attracted the attention of researchers due to their low density with high specific mechanical strengths, convenience, and renewability. The current work efforts to make a development in the current existing helmet manufacturing procedure and materials used to have better mechanical properties as well as to enhance the compatibility between fibers and the matrix. The composites are ready with the unsaturated polyester matrix and fibers such as, reinforced composite materials and glass fiber using hand lay-up method with suitable proportions to result in helmet shell construction. The fabricated helmet are planned to estimate its mechanical properties such as tensile strength, impact strength and compression strength. Keywords: Fibers reinforced composite materials, glass fiber, manufacturing methodology, fabricated helmet, tensile strength, impact strength and compression strength. 1. Introduction Fiber-reinforced polymer composites are similar to wood, as they consist of reinforcing fibers embedded in a polymer matrix as well. Within fiber-reinforced polymer composites, the distinction between short and continuous fibers is important. Short fiber composites, are mainly used for non-structural complex parts. One of the most common short fiber composites is injection moulded glass fiber - polypropylene. REIN4CED however, focuses on high performance continuous fibers. To fully exploit the potential of fibers, fibers need to be aligned to the load direction over the entire length of the object. Commonly used continuous fibers are carbon, glass and aramid. The combination of high-performance continuous fibers and a polymer matrix results in a composite material which is a lightweight alternative for steel and aluminium for structural applications. Compared to plastics, fiber-reinforced composites have outstanding mechanical properties per weight. The most interesting features of fiber-reinforced polymer composites are: High mechanical properties per weight for lightweight structural applications Excellent fatigue performance Good impact resistance Corrosion resistant Large design freedom and near net shape production Both small- and large-series production possible 2.
