Abstract

This paper presents the stress analysis of spur gear made from natural fiber reinforced polymer matrix composite material. These gears provide better alternative for replacing metallic gears. In this work epoxy resin is used as matrix material. Fly ash, coir fiber and carbon nano tube are used as reinforcement materials. Response surface methodology, one of the design of experiment approaches, is used to arrive the different material combinations. Static structural analysis is performed to obtain stress distributions and deformation. Analysis of variance (ANOVA) is employed to get optimized combinations for maximum stress. Analysis reveals that these gears can be used in low strength applications.
