Abstract: An antenna reflector, in particular for a spacecraft and especially for a satellite, includes a shell provided with a first surface that is reflective, and a reinforcing system this is arranged on a second surface of the shell, opposite said first surface. The antenna reflector further includes at least one structural portion having a generally circular shape.

Abstract: An assembly comprising two parts temporarily connected by a connecting element surrounding the assembly. The connecting element being subjected to an internal deformation stress. The assembly having stress-keeping means with controlled stress relief, which connect two opposite ends of the connecting element so as to counteract the internal deformation stress. The assembly includes attaching means for attaching the connecting element to each of the parts. The attaching means includes at least two layers of cured adhesive which respectively coat the parts and make a surface connection between each of these parts and the connecting element. The internal deformation stress is at a sufficient level to enable the connecting element to be unsecured from the parts by extending to a rest position, when the stress-keeping means are controlled so as to release the ends of the connecting element.

Abstract: The invention provides a method for making a composite (10) including two skins (14) of composite material bonded on either side of a core (12) having the form of a honeycomb type panel, including a step of firing the skins (14) onto the core (12) to simultaneously carry out hardening of the skins (14) and bonding of the skins (14) with the core (12), characterised in that it consists in placing a rigidifying layer (22) between the core (12) and at least one skin (14).

Abstract: A method for making a temporary connection between two parts (10, 12), comprising the following successive steps: placing a connecting element (40, 40?) into an operating position wherein said connecting element surrounds the assembly formed by said parts and is subjected to an internal deformation strain; locking the position of said connecting element by stress-keeping means (52?) with controlled relief; connecting said connecting element (40, 40?) to each part (10, 12) by attaching means (36, 38); and wherein said internal deformation stress is at a sufficient level to enable the connecting element (40, 40?) to be unsecured from said parts (10, 12) by extending to a rest position, during a release control of said stress-keeping means (52?).
