|Summary||An experimental investigation was conducted to study the crushing behavior of aluminum tubes wrapped with fiber reinforced plastic composites. The influence of surface treatments of aluminum on failure mode and on the energy absorption capacity of multi-material tubular elements was determined under dynamical compression conditions. No significant differences were observed on the energy absorption capacity whatever the surface treatments are. The composite reinforcement applied onto aluminium tube with 2 mm thickness, constraint to deform it, in a favorable manner for dissipating energy and a better deceleration is obtained.
||Keywords|| multi-material, surface treatments, energy absorption, circular tube.
