Experimental and Numerical Study on Effect of Fibre Orientations on Residual Elastic Properties in Glass Fibre Laminates.

Abstract

This work combines experimental and numerical studies on the free vibration of glass fiber-reinforced polymer (GFRP). The effect of fiber orientations of GFRP composite laminated materials has been investigated by vibration characteristics. Three symmetric laminates having [(0/90)3] S, [(30/-60)3] S and [(45/-45)3] S fiber orientation angles were prepared using plain weave glass fabrics as reinforcement. Residual elastic characteristics of GFRP composite laminated materials have been investigated concerning the effect of angle ply orientations. The vibration study is carried out using an accelerometer and numerical analysis was carried out using ABAQUS with different boundary conditions. It is observed from the results that GFRP with different fiber orientations yields different residual elastic properties by considering the same load, size & shape constraints. It is observed from the result that GFRP with [00/900]3 fiber orientation Yields high (residual elastic) strength when compared to other degrees of orientations for the same load, size & shape addition.
