Abstract (en)
[origin: WO2013186476A1] The invention relates to a method for producing foam panels, especially for the field of aeronautics, comprising the steps consisting in: providing at least two blocks of foam material (19a, 19b); arranging said two blocks on at least one ply of dry fabric (21 a, 2b), a so-called "base ply", maintaining a space (23) between said two blocks; folding said base ply (21 a, 21 b) around said two blocks (19a, 19b) so as to envelop them; filling the space (23) between the two blocks (19a, 19b) with at least one so-called "reinforcing" ply of fabric (211a, 211b, 212a, 212b); covering the base ply (21a, 21b) with at least one so-called "covering" ply of dry or fresh fabric (29), on the side where the reinforcing ply was inserted (211 a, 211 b, 212a, 212b); injecting the assembly produced in this way with resin; and baking the assembly produced in this way.
