Method of manufacturing a blank made from thermoplastic composite material, associated manufacturing tool and use of the method to produce structural aircraft parts

摘要

A method of manufacturing a blank made from thermoplastic composite material, in which a pressure and temperature cycle is applied by pressing on top of a compacting plate that is itself on top of a stack of fibers including continuous fibers pre-impregnated with a thermoplastic resin, which stack has been previously placed on a board with the film enveloping the stack being brought into contact with fixing blocks arranged at the periphery of the board, 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 allowing the gas(es) present in the stack to escape through at least one opening left in the enveloping film and then through at least one emerging channel formed in the compacting plate and/or in the board and/or in the fixing blocks.
