This article deals with the experiment and numerical simulation of the crash of composite tubes made of 2,5D-braided composite. In a first part, we present the material characterization at different strain rates as well as the results of tubes which have been tested in a drop-weight tower. In a second part, we describe the bi-phase material model which has been developed. It is based on Drozdov’s modelling for thermoplastic matrix and on the kinking modelling for fibers. In a last part, we present the experiment and numerical simulations correlations and we will conclude more particularly about the good predicting the value of energy absorption.
