What is it about?

This paper is about absorbing impact (crash) energy with new reinforcement techniques in sandwich composites.

Why is it important?

Experimental results of medium velocity impact tests are carried out on several arrangements of reinforced foam/braided composite structures. Post-mortem tomography analysis delivered very rich information which shed light on the damage mechanisms that the composite structures underwent. In addition, energy absorption are computed from fast cameras pictures are compared to those of dynamic crushing tests (reported in a companion paper).
