Abstract
A device for absorbing kinetic energy for an aircraft structural element undergoing a dynamic impact. The device includes an outer enclosure made from a braided composite material configured to preserve its integrity after an impact, and a foam core contained in the outer enclosure and to at least partially fill the outer enclosure. The foam core configured to at least partially absorb the kinetic energy generated by the impact. Reinforcing elements include at least one dry composite fiber preform integrated into the foam core to dissipate, in combination with the foam core, the kinetic energy generated by the impact. A method for integrating the device for absorbing kinetic energy.
