Abstract

The invention relates to a structural element (2) capable of recovering static compressive forces along an axis Z. Said structural element comprises two profile members (21, 22) made of fibrous composite material that extend along the axis Z, said two profile members being rigidly connected to one another, at a joining area (25), by means of so-called transverse fibers (26) that are perpendicularly placed at an interface between said two profile members, and moreover placed perpendicular to the axis Z, so that a shock along the axis Z causes a delamination of said transverse fibers in order to absorb the energy.
