METHOD FOR MANUFACTURING FLAN OF THERMOPLASTIC COMPOSITE MATERIAL, ASSOCIATED TOOLING FOR MANUFACTURING AND APPLICATION OF PROCESS TO REALIZATION OF AIRCRAFT STRUCTURE PARTS

摘要

The invention relates to a novel method for manufacturing a blank made of a thermoplastic composite material in which a pressure and temperature cycle is applied, by pressure on the top of a compacting plate (13) itself above a stack of fabrics (20) of pre-impregnated continuous fibers (20) of a thermoplastic resin, stack (20) previously placed on a marble (12) with contacting of the film (2) enveloping the stack (20) with tabling wedges (14) arranged at the periphery of the marble (12) and, by heating the stack, so as to reach at least the melting temperature of the resin while leaving the film infusible and smooth, and evacuating the gas (s) present in the stack by at least one opening (O) left in the wrapping film and then by at least one opening channel (42) formed in the compacting plate (13) and / or in the marble (12) and / or in the shims (14).
