摘要

This paper investigates the effect of fibre orientation on the flexural strength of fibre reinforced -epoxy laminated composite material, with the variation in the orientation of the reinforced fibres there will be a substantial variation in the flexural strength of the laminated composites. In the present paper fabrication of glass fibre reinforced laminated composites and graphite fibre reinforced laminated composites with varying orientation of reinforced fibres were prepared using the hand layup, vacuum baggage technique and these specimens are subjected to 3 point static bending testing the investigations are carried out as per the ASTM standards. Using the load - deflection graph the maximum load, maximum deflection and the flexural strength of the specimen for different laminated composites is evaluated and the appropriate conclusions are drawn.
