Experimental investigation of two-dimensional delamination in GFRP laminates

The 2D delamination behavior of composite laminates under quasi-static out-of-plane opening loading has been experimentally investigated. A circular embedded pre-crack was introduced in the center and at the midplane of the laminates. To investigate the effect of the fiber architecture on the fracture behavior, six different types of fabrics were selected. Increasing load–displacement curves were obtained due to the increasing crack front length...
