Abstract
The present disclosure is related to a method for producing a cellular panel which includes a cellular structure sandwiched between first and second stiff skins. The method includes the following steps: preparing at least two blocks of cellular material; disposing the two blocks on a base ply of dry fabric, while maintaining a space between the two blocks; folding the base ply around the two blocks so as to envelop the two blocks; filling in the space with a reinforcing ply; covering the base ply with a covering ply, on a side where the reinforcing ply has been introduced; injecting resin to an assembly obtained in the previous step; and curing the assembly.
