Modelling of Failure Mechanism in Unidirectional Carbon Fiber-Reinforced Polyamide Composites Using Cohesive Zone Model

摘要

In this paper, the damage mechanisms in unidirectional composites is investigated. The model distinguish the fiber and the matrix at mesoscopic scale. The load transfer on intact fibers neighbouring a broken fiber is evaluated. The fiber-matrix interface debonding is modelled using cohesive model in the commercial code ABAQUS. The aim of this work is to describe and analyse the micromechanics failure of carbon reinforced polyamide composites and the associated load transfer in order to predict the lifetime of such composite materials.
