THE EFFECT OF ARRANGEMENT AND SYMMETRY IN GLASS AND CARBON FIBER REINFORCED EPOXY MATRIX HYBRID COMPOSITE ON FLEXURAL TEST.

Abstract

Polymer matrix composites have wide engineering applications where strength-to-weight ratio, high dimensional stability, high chemical resistance, low cost and ease of fabrication are required. Hybrid composites offer a range of mechanical properties that are difficult to achieve in composites containing one type of fiber. Recently, hybrid vehicles have been established as high-efficiency, high-performance structural materials and their use is rapidly increasing. Hybrid composites are typically used when combinations of properties of different types of fibers need to be achieved, or when longitudinal and lateral mechanical performance is required. In this study, the bending strength of a carbon- and glass-fiberreinforced hybrid epoxy matrix composite was studied and to know the effect of the arrangement of glass and carbon fibers in building composite materials on the bending strength with respect to symmetry by angles and symmetry by layers. The results showed that the bending strength of the hybrid composite symmetric in the corners and asymmetric in the arrangement of the layers of carbon and glass has improved significantly compared to the hybrid compound symmetrical in the angles and symmetrical in the arrangement of the layers of carbon and glass
