Abstract:
1. A structure which is inflatably deployable and stiffenable after being deployed, which comprises a flexible membrane, said membrane comprising at least one layer of a composite, said layer having a first face and a second opposite face, and at least one polymer film that is permeable to visible radiation and that covers the first face of the composite layer, said composite being formed from a fibrous material impregnated with a composition including a non-polymerized epoxide or epoxy/acrylate resin and a photoinitiator for initiating the polymerization of the resin upon irradiation of the membrane with a visible radiation and thereby obtaining the stiffening of the structure, wherein the photoinitiator is an iron-arene complex salt of formula (I): in which A represents an arene group while X represents a non-nucleophilic anion.
