Tensile failure analysis and residual strength prediction of CFRP laminates with open hole

Failure patterns and damage mechanism of CCF300/QY8911 and T300/QY8911 composite laminates with open hole had been investigated experimentally and numerically. CCF300/QY8911 composite laminates with a weak interfacial strength produced massive delaminations and splitting bonds which relieved the stress concentration, thus having a higher strength. T300/QY8911 composite laminates with a higher interfacial strength presented to be brittle fracture...
