This paper discusses the application of a methodology that was described earlier. The methodology has been conceived, calibrated, validated and extrapolated for elastic-plastic-brittle, multilayered and multi-material composite sandwich wall and sandwich core models for the numerical crashworthiness prediction of composite components. The new models have been implemented into the PAM-CRASH simulation program, and validated on component crash tests. The effects of combining brittle carbon and plastic Kevlar fibers in the sandwich facings of the tested structures have been studied. The models are extrapolated to the numerical crash simulation of a full size composite passenger car cabin.
