Abstract

The influence of the porosity on the impact damage of CFRP laminates was investigated. A finite element analysis model is established by using ABAQUS software combined with the sudden stiffness degradation model. The failure criterion of the impact damage of the fabric fiber reinforced composites is proposed by improving the fiber and matrix damage failure criterion, based on the failure criterion that is suitable for the undirectional composite laminates. The impact damage of longitude fiber failure, latitude fiber failure, matrix crushing and delamination were considered for the fabric carbon fiber reinforced epoxy composites laminates. Basic strength parameters of composites are used to evaluate the mechanical properties of CFRP laminates with different porosities. The impact damage area of CFRP composites laminates are simulated accurately.
