Title (EN) DEVICE FOR MAINTAINING AND DEPOSITING A THERMOPLASTIC COMPOSITE MATERIAL ON A SHAPING TOOL AND METHOD FOR MAKING A COMPOSITE PART
(FR) 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
Abstract: front page image
(EN)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.
(FR)Une ou plusieurs feuilles thermoplastique (2) sont posées sur un outillage (13) plat ou courbe, et des bande de polymère sont posées et pressées sur les feuilles (2). Elles sont maintenues par des pompes d'aspiration (8) dont les orifices (4) débouchent dans un volume clos ou sensiblement délimité par un joint d'étanchéité (3) et occupé par un tissu drainant (7). Le traitement de chauffage concomitant à la dépose pour durcir ou consolider le pré-imprégné amollit les feuilles (2), les déforme à la courbure de l'outillage (13) et les incorpore à la structure du pré-imprégné. Application aux procédés de drapage de pièces en matière composite.
