The model coupling adhesion, unilateral contact and friction, developed by M. Raous, L. Cangémi and M. Cocou, is extended here for studying propagating cracks in fiber-reinforced composites. The brittle fracture of the bulk materials (fiber and matrix) is described by a time-independent version of the model. In this case, jumps in the evolution of the solution may occur and a dynamic formulation has to be used. This is performed by adapting a dynamic formulation due to J.J. Moreau and M. Jean to this problem. Numerical simulations of 3D fracture of composite materials are then presented.
