On the mixed mode I/II delamination R-curve of E-glass/epoxy laminated composites

The main effort of the current study is to propose a procedure for prediction of delamination resistance curve (R-curve) of laminated composites under mixed mode I/II loading conditions based on the experimental observations. Hence, two material systems, i.e., E-glass/epoxy and E-glass/MWCNTs-toughened epoxy were tested at a wide range of mixed mode I/II delamination to present R-curves. Each R-curve was characterized by fiber-bridging zone...
