    Delamination is a common failure mode of composite structures due to their often low interlaminar fracture resistance. The use of conservative design approaches to prevent crack initiation, leads to design that are not optimal. The alternative approach is to allow damage initiation and some/limited crack propagation in the structure. Such an approach requires the use of composite materials with high damage tolerance. In the present work, we aim to increase the fracture resistance of unidirectional composites by large scale fibre bridging. It is shown that the steady-state fracture resistance can be increased several times by modifying the fibre sizing and matrix material.
