Effect of glass hybridization and staking sequence on mechanical behaviour of interply coir-glass hybrid laminate

The interest in fibre-reinforced polymer composites is growing rapidly due to its high performance in terms of mechanical properties, significant processing advantages, excellent chemical resistance, low cost, and low density. The development of composite materials based on the reinforcement of two or more fibre types in a matrix leads to the production of hybrid composites. In the present work, woven coir-glass hybrid polyester composites were developed and their mechanical properties were evaluated for different stacking sequences. Scanning electron micrographs of fractured surfaces were used for a qualitative evaluation of interfacial properties of woven coir-glass hybrid polyester composites. These results indicated that coir-glass hybrid composites offered the merits of both natural and synthetic fibres.
