Finite element simulations and experiments to determine the residual damage of a CFRP composite material after ballistic impacts
conference paper
The use of lightweight systems is essential for future combat systems. More and more steel structures are replaced by composite structures. This also influences the vulnerability of the platform. A finite element material model is created in Autodyn of the carbon fiber reinforced plastic (CFRP) AS4/3501 in order to predict both the residual velocity and the damage after ballistic impacts. This paper will explain the used input parameters, of which most are obtained from material tests.
Furthermore, results are shown from ballistic impact experiments and simulations, followed by analysis of the residual damage in both the experiments and the simulations. The paper will show that the
simulated residual velocities are consistent with velocities measured in experiments. Furthermore, the predicted residual damage is in the same order of magnitude as the observed residual damage.
