Abstract

Filament winding is a composite material fabrication technique that is used to manufacture concentric hollow components. In this study Carbon/Epoxy composite drive shafts were fabricated using filament winding process with a fiber orientation of [852/±452/252]s. Carbon in the form of multifilament fibers of Tairyfil TC-33 having 3000 filaments/strand was used as reinforcement with low viscosity epoxy resin as the matrix material. The driveshaft is designed to be used in SAE Baja All Terrain Vehicle (ATV) that makes use of a fully floating axle in its rear wheel drive system. The torsional strength of the shaft was tested and compared to that of an OEM steel shaft that was previously used in the ATV. Results show that the composite shaft had 8.5% higher torsional strength in comparison to the OEM steel shaft and was also lighter by 60%. Scanning electron microscopy (SEM) micrographs were studied to investigate the probable failure mechanism. Delamination, matrix agglomeration, fiber pull-out and matrix cracking were the prominent failure mechanisms identified.

Abstract

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 [90°/0°/90°/0°/90°] 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.
