The invention concerns a device for absorbing kinetic energy for an aircraft structural element that may undergo a dynamic impact, this device 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 (21), said foam core (22) being capable of at least partially absorbing the kinetic energy generated by the impact, and reinforcing elements (30) integrated at least partially into the foam core in order to dissipate, combined with the form core (22), the kinetic energy generated by the impact; - the reinforcing elements (30) comprising discontinuous threads (32) inserted into the foam core (22) by stitching, and the discontinuous threads (32) each include an L- or T-shaped head (33), folded down outside the outer enclosure (21).
