Abstract (EN):
In this work a micromechanical model that takes into account the statistical nature of fibre strength present in composite materials, as well as the proper constitutive response of the resin and fibre-matrix interface, is developed and used to determine the failure behaviour of hybrid and non-hybrid composite materials. The model is able to capture failure mechanisms in the three main components of a composite material: fibres, matrix and fibre-matrix interface. The understanding of the failure mechanisms is used to modify the tensile behaviour of hybrid composites to have a pseudo-ductile behaviour.
