METHOD FOR FINISHED-RIB COMPACTING A THERMOPLASTIC COMPOSITE PART WITH CONTINUOUS FIBRES

摘要

The invention relates to a method for producing a structural part including at least two flanges extending in intersecting planes, consisting of a composite thermoplastic material with a fibre reinforcement including at least two plies of continuous fibres, said fibres extending from one flange to the other, wherein said method includes: a cutting step consisting of cutting the at least two plies in a fabric and/or a web of fibres preimpregnated with a thermoplastic resin; a drape-forming step for assembling the plies in order to create a blank; and a consolidation step for compacting said blank into the defined shape of the part by subjecting the same to a predetermined temperature and pressure cycle. The invention also relates to equipment for implementing the above method. Such equipment includes a rigid punch and a rigid die so that the closing of the equipment forms a sealed chamber with the shape of the part being formed between the punch and the die.
