Mechanical characterization of orientations of polyester/glass fibre reinforced polyester matrix composites

Abstract

The purpose of this study is to evaluation of the mechanical characterisation such as tensile, compression and bending test and to conduct wear test. This study focus on preparation and testing of Polyester resin using glass fibre for different orientation. The Mechanical properties of the polyester changes gradually by changing the layers of fibres and for different orientation of glass fibre the property differs. The laminate is prepared of size 300*300*4mm size and specimens are prepared as per ASTM standard, different layers of glass fibres are one, two and three layers and the orientation of glass fibre is 30o, 60o, and 90o. The glass fibre used is in fabric form. From the results which were obtained we can observed that three layers glass fibre for 90o orientation has improved tensile strength and the compressive strength is found to be more for 600 orientation of glass fibre.
