ABSTRACT:
A method for producing a sandwich-type panel with structural and acoustic properties and formed of a core with an open cellular structure. The method includes the steps of forming first and second skins by superimposing and hot-pressing at least two fabric plies of mineral or synthetic fibers impregnated with a thermoplastic resin, of forming in one of the skins perforations with a diameter of between about 0.5 and 1.5 mm, with a vacuum proportion of empty spaces on the surface of the skin of between about 10 and 25%, of after preparation of the skins applying on one face of the skins an epoxy adhesive coating, of forming a sandwich including the open cellular structure with the two skins on its opposing faces, and then of hot-pressing the sandwich at an appropriate temperature so as to polymerize the adhesive. During hot-pressing the pressure and duration are set so as to avoid any full or partial obstruction of the perforations of the perforated skin.
