Analysis and Characterization Helm Based on Hyacint Water Composites

Abstract

Material engineering in the field of natural fiber composites has potential prospects. The availability of natural resource was very abundant. Composite with natural fiber reinforcement was called Bio composite. The promising natural resource were water hyacinth. Water hyacinth was a source of fiber that can be used optimally as a filler in composites. Bio composite properties are be affected by several factors including filler volume, process parameters and filler interface properties in the matrix. The use of water hyacinth bio composite was developed as a substitute for shipbuilding materials, board and leg sockets for prosthetic limbs. This research identified the nature of fibers as fillers in the application of motorcycle helmet that meet Standar Nasional Indonesia (SNI). Hyacint fibers are made from water hyacinth plants, the plant is dried by sun shine. The material was crushed into powder and woven fibers with yarn spinner and the both materials are mixed using resin. The bio composite was tested by tensile test and impact test using variations weight fraction. The best high strength of bio composite was used as material helm shell by using a vacuum bagging system. The value of Impact absorption strength and penetration testing will be tested on helmet shell composites. Tests conducted on bio composite helmets are carried out to meet standard safety according to SNI 1811: 2007.
