Abstract: The invention proposes a method for manufacturing a grille for a cascade type thrust reverser, of a jet engine, said method including the following steps:

a) manufacturing a first component comprising continuous or long fibres, pre-impregnated by a thermoplastic or thermosetting resin;
b) manufacturing, subsequently or together with step a), a series of second components each including discontinuous fibres, pre-impregnated by a thermoplastic or thermosetting resin, step b) being carried out such that the second components are, on the one hand, arranged transversally with respect to a longitudinal direction of the first component on at least one side of the first component and, on the other hand, spaced from one another according to this longitudinal direction, so as to form a comb-shaped structure, wherein the second components are consolidated to the first component.

Abstract: The invention relates to the thermal creation of a part, including steps of: using at least one first and one second metal plate (30, 31), hollow-forming the first plate so as to form at least part of said inner wall, and hollow-forming the second plate (31) so as to form at least part of said outer wall. During the forming, the shapes of the first and second plates are adjusted such that they can be placed in contact with each other while leaving a space therebetween inside said periphery, and then the first and second plates are placed in a low-pressure and/or controlled-atmosphere chamber (65), where said plates are brought together and peripherally sealed together such that, in said space, a low-pressure and/or controlled-atmosphere enclosure is created.
