Evaluation of Flexural and Compressive Strength of E Glass/Jute and E Glass/Banana Hybrid Epoxy Hollow Composite Shafts

摘要

In this study hybrid composite hollow shaft for applications with dominant flexural and compressive load is developed. Numerical analysis is carried out to understand the failure of the proposed shafts. Azzi-Tsai-Hill failure theory is used to check for failure before fabricating the shafts. To validate the results of numerical analysis, two different hybrid composite shafts were fabricated on a filament winding set-up. A stacking sequence of [9070°/9070790°] was used during fabrication. Hybridization was achieved by winding alternate layers of synthetic and natural fibers with epoxy, starting with E glass as the first layer followed by jute fibers while in the second shaft; banana fibers replaced the jute fibers. Compression and flexural tests were conducted on the hybrid shafts according to ASTM standards. Test results indicate that composite shafts having jute fiber along with E glass fiber could take more load, both in compression and in flexural loading conditions.
