Axial Energy Absorption of Kenaf Yarn Winding Cylindrical Composites

摘要

This present work investigates the composites reinforced with kenaf fiber to fabricate the cylindrical tubes. According to the literature survey, it is found that lack of study research of producing the cylindrical composites with filament winding method using kenaf fiber. Therefore, this work used long fiber wetted with epoxy resin and then wound around the cylindrical mould. Three different winding angle orientations are used such as 00, 50, and 100. Then, the tubes are compressed Quasi-statically using a constant speed 1.5 mm/min crosshead displacement. Force displacement curve are obtained and the area under the curve represented the energy absorption performance. It is found that the capability of energy absorption decrease when higher winding angles is used. At the same time, the collapse mechanisms are almost similar with different types of fiber orientations angle.
