Abstract
A pyrotechnically-ruptureable composite structural component, intended to transmit forces between first and second structural elements, has an elongate pyrotechnic detonation separation component incorporated in the structural component for breaking the structural component and separating the first and second elements. The structural component has a first part in which the pyrotechnic separation component is incorporated and which is able to be connected to the first element, and a second part that connects to the second element. The first and second parts are rigidly assembled via their free ends, which are the opposite ends to the first and second elements respectively. The rigid assembly has a damper arranged between the free ends of the first and second elements so as to damp a detonation shock propagating to the free end of the first part when the pyrotechnic separation component is detonated.
