  Abstract

In order to study the damage mechanism of carbon fiber composite laminates, an experimental and numerical investigation has been carried out to study the dynamic perforation behaviors of composite plates subjected to low velocity impact. The numerical simulations of the progressive damage process for different plates under different impact energies are based on the Multi-Continuum Theory (MCT). 3D FE models with cohesive ply element was established, and the failure processes of the matrix component and the fiber component in the laminates were individually simulated based on MCT failure criterion. By introducing two parameters, the penetration limit and the perforation limit, the damage process of each plate was showed in the form of Energy profile diagram (EPD) which was used to compare the impact resistance abilities of three kinds of composite plates The simulation results were in good agreement with the experimental results. The results revealed that there is a greatest impact resistance in mixed lay-up plate. Compared to the 0-degree plates and the orthotropic plates, the damage strength of the mixed lay-up plate has increased by 252 % and 120 % respectively.
