The invention concerns a device for absorbing kinetic energy for an aircraft structural element that may undergo a dynamic impact, comprising: - an outer enclosure (21) made from a braided composite material capable of preserving its integrity after an impact, - a foam core (22), contained in the outer enclosure and capable of at least partially filling said outer enclosure, said foam core being capable of at least partially absorbing the kinetic energy generated by the impact, and - reinforcing elements including at least one dry composite fibre preform (30) integrated into the foam core to dissipate, combined with the foam core, the kinetic energy generated by the impact. The invention also relates to a method for integrating said device for absorbing kinetic energy.
