The present paper evaluates the crashworthiness simulation techniques of CFRP/honeycomb composite structures for automotive applications. A basic methodology for strength and failure analyses of CFRP/honeycomb sandwich materials is outlined. The new material models have been implemented into a crashworthiness simulation code, PAM-CRA-SHTM. After calibration of the material models and parameters on laboratory coupon tests and validation on simple component crash tests, the models are extrapolated to the numerical crash simulation of a full size composite prototype passenger car main-frame. The numerical results are satisfactorily correlated with experimental results.
