Einhüllanlage zur Herstellung von mehrlagigen Strukturen aus Kompositmaterialien

摘要

In order to produce multilayer structures made of composite materials, by draping pre-cut elementary layers over a forming die (12), an installation is proposed comprising, in addition to the forming die (12), a gripping tool (16) capable of being mounted, for example, on the articulated arm of a robot. The forming die (12) comprises a flexible membrane (28), equipped with suction suckers (58) which grip the pre-cut elementary layers. A vacuum circuit (48) enables the membrane (28) to be pressed up against a counter-shape (26) placed behind the latter, in order to shape the elementary layer picked up. When the tool (16) is brought onto the die (12), a pressure source (52) acts on the membrane (28) in order to compact the elementary layer on the die. A suction system (76, 82) keeps this layer on the die, after releasing the suction via the suckers (58).
