摘要 |
According to the invention, one or more thermoplastic sheets (NdT: “feuilles thermoplastique” in the original) (2) are applied on a flat or curved tool (13), and strips (NdT: “des bande” in the original) of a polymer are applied and pressed onto the sheets (2). They are maintained by suction pumps (8), the orifices (4) of which open into a closed volume or one substantially delimited by a sealing joint (3) and occupied by a draining fabric (7). The heating treatment concomitant to the deposition to harden or consolidate the prepreg softens the sheets (2), distorts them to the curvature of the tool (13) and incorporates them in the structure of the prepreg. Application to methods of draping parts with composite material. |
