Abstract

Interlaminar fracture toughness and fracture mechanism in carbon fiber reinforced nylon laminates have been investigated. Mode I interlaminar fracture toughness tests are carried out on the double cantilever beam (DCB) specimens made of four kinds of angle-ply laminates. These laminates exhibit unstable ''stick-slip'' crack propagation. In order to obtain the continuous G(I) resistance curve (G(I)-R curve) describing the stick-slip behavior, one modification is made to Kageyama's (1987) modified compliance method. From the continuous G(I)-R curves, it is found that the stable delamination is characterized by flat region of G(Istable) approximate to 1200 J/m(2) for all lay-ups except for 60 degrees//-60 degrees specimen which shows a rising G(I)-R curve to final failure. The interlaminar fracture toughness of these composite laminates is considerably higher than that of carbon/epoxy laminates. Based on the continuous G(I)-R curves and the observation of the fracturesurfaces, a mechanism is proposed in which the unstable stick-slip behavior is explained by the development of the large scale bridging of fiber-bundle or layer and its breakage.
