Track: Design and Analysis

Abstract

 Polymer composite, presently one of the most promising and innovative fields of research, and the importance of using biodegradable fibers as reinforcement in polymer composite material is growing rapidly. In this era of excessive depletion of petroleum resources and for new green environmental regulations, natural fiber-based composites can be crucial for the environment. In this study, a composite has been produced using reinforcement of glass fiber and rice straw and a matrix of epoxy resin. Mechanical properties of the composite such as impact and flexural properties have been investigated. The fiber orientation has a great impact on the mechanical properties of these composites. Impact and flexural strength both were found to be higher at 0° fiber orientation.  Flexural strength rapidly decreased as the orientation angle of fiber increased from 0°  to 90°. On the other hand, impact strength decreased up to 45°  and then it again increased until the orientation angle reaches 90°.
