VERFAHREN UND VORRICHTUNG ZUR HERSTELLUNG EINES VERBUNDBAUTEILS MIT KOMPLEXER FORM

摘要

The invention relates to a method for producing a three-dimensional composite component from a thermoplastic matrix with continuous reinforcement, characterized in that it comprises the steps consisting in: a. obtaining a preimpregnated fibre preform (100) by three-dimensional knitting; b. placing the preform on the male mould form (120) or in the female mould form (110) of tooling, with the mould forms between them defining a sealed closed cavity; c. closing the tooling so as to apply a first pressure to the preform; d. raising the cavity to the melting temperature of the polymer with which the preform is impregnated, maintaining the first pressure; f. cooling the cavity containing the preform down to a temperature suited to demoulding, maintaining the second pressure; g. opening the mould and demoulding the component.
