<p>Compression moulding method for composites consisting in forming a dough (2) under pressure consisting of an amalgam of non-woven fibres randomly mixed and associated, in a defined proportion, with a thermosetting or thermoplastic material. The preparation of the dough (2) consists in mixing said fibres and said thermosetting or thermoplastic material, in a vacuum, while said forming operation is carried out by introducing the dough (2) into a mould (1) designed and dimensioned to withstand high pressures, having a moulding cavity (11) in the form of a part (P) to be produced and provided with at least one well (12) configured so as to accommodate, tightly, a plunger piston (13; 36; 48), which, by sliding, can pressurize (F) the dough (2) in the cavity (11), and therefore form the latter in the mould (1).</p> |
