| 20100117264 | COMPRESSION MOULDING METHOD FOR COMPOSITES, AND MOULD DEVICE FOR IMPLEMENTATION THEREOF - Compression molding method for composites including the step of forming a dough under pressure, including an amalgam of non-woven fibers randomly mixed and associated, in a defined proportion, with a thermosetting or thermoplastic material. The preparation of the dough includes mixing the fibers and the thermosetting or thermoplastic material, in a vacuum, while the forming operation is carried out by introducing the dough into a mould shaped and dimensioned to withstand high pressures. There is a molding cavity in the form of a part to be produced and provided with at least one well configured so as to accommodate, tightly, a plunger piston, which, by sliding, can pressurize the dough in the cavity, and therefore form the latter in the mould. | 05-13-2010 |
