Assessment of open hole flexural strength and progressive damage mechanism of CFRP composite as a function of stacking sequence

An experimental study was carried out to evaluate the flexural behaviour of CFRP composite laminate with introduction of open hole as well as by varying stacking sequence. Open hole is required in laminated composites to assemble the components through mechanical fasteners. Degradation in strength was observed due to the presence of a hole. Six stacking sequences have been analysed: [0]8, [90]8, [0/90]2s, [90/0]2s, [02/902]s, [902/02]s in which...
