DISPOSITIF DE MAINTIEN ET DE DEPOSE DE MATIERE COMPOSITE THERMOPLASTIQUE SUR UN OUTILLAGE DE MISE EN FORME ET PROCEDE DE FABRICATION D'UNE PIECE COMPOSITE

摘要

According to the invention, one or more thermoplastic sheets (2) are applied on a flat or curved tool (13), and strips of a polymer are applied and pressed on the sheets (2). They are maintained by suction pumps (8) having openings (4) giving into a volume that is enclosed or essentially defined by a seal (3) and includes a draining cloth (7). The heating process, which is simultaneous with the deposition for curing or reinforcing the pre-impregnated material, softens the sheets (2), deforms them according to the curvature of the tool (13), and incorporates them into the structure of the pre-impregnated material. Application in methods for draping parts of composite materials.
