<p>Components of composite material are made from pre-impregnated or laminated sheets (1) by inserting the sheets in a closed moulding cavity (2) defined between at least two adjacent half-moulds (3, 4) and following spreading of a separating agent, wherein at least one half-mould has a die (5) of a shape matching that of the component to be produced, and then by introducing into the moulding cavity, preferably into a zone (15) insulated from the half-moulds and from the sheets of composite material by the interposition of covering sheets (11, 12), a pressurized fluid material (10) adapted to compact the sheets (1) on the die (5) and to heat the sheets (1) to the polymerization temperature; laminated sheets are softened directly between the half-moulds (3, 4) which form counter-electrodes connected to a high frequency generator (20). <IMAGE></p> |
