Investigation of Mechanical Behaviour of Glass Fibre Based SiC Polymer Composites

Abstract

Silicon Carbide/GFRP reinforced matrix composite and SiC matrix composite has been developed by using hand layup and resin casting methods respectively. The GFRP reinforced polymer composite is made by sandwiching two layers of GFRP in between the SiC material. The resin used for the preparation the samples are epoxy and polyester, for both Sic/GFRP composite and SiC composite. An Arcan fixture with butterfly specimen is used to measure the fracture occurring in various modes of the polymer composite. The objective of the proposed testing method is to determine the variation in the stress value depending on the resin material as well as the influence of GFRP in the strength of SiC polymer composite. Results from the tests are analyzed to show that the polyester resin is better for shear strength, in both Sic/GFRP reinforced and SiC composite material.
