Abstract

In the present research the influence of large-scale fibre bridging on the crack growth rate in mixed-mode delamination of unidirectional glass-epoxy composites was investigated. The study employed double cantilever beam specimens subjected to cyclic even and un-even bending moments, i.e., steady-state specimens. In the study, the bridging ligaments at fracture process zone (developed after several cycles) were cutoff and the tests are then subject to the same previous load. This led to an accelerated crack growth rate. Varying the length of the bridging zone (while keeping everything else, e.g., load, the same) has a strong effect on the crack growth rate.
