Abstract
This paper deals with the experimental investigation and the numerical modelling of fibre mortar composite interface. This study focuses on the determination of failure types and the characterisation of mechanical behaviour at a fibre mortar-composite interface. The mechanical properties of fibre mortar are determined through laboratory tests. Experiments are carried out using a series of pull-out and shear tests to study the behaviour of composite/glue/fibre mortar assemblage. Numerical simulations based on the finite element method are used to predict the interface damage parameters as well as mixed mode crack initiation and propagation at the fibre mortar-composite interface. An interfacial decohesion model based on the indirect use of fracture mechanics is used to simulate the damage process. The model assumes a bilinear softening behaviour of the interfacial provided with stress-relative displacement laws. The interface parameters at the interface between fibre mortar and composite are evaluated and the failure mode determined.
