摘要： The invention relates to a novel method of manufacturing a blank made of a thermoplastic composite, in which a pressure/temperature cycle is applied by pressing on the top of a compacting plate (13) which is itself on top of a stack of fabrics (20) made up of continuous fibres (20) pre-impregnated with a thermoplastic resin, the stack (20) being placed beforehand on a bed (12) with contacting of the film (2) surrounding the stack (20) with fixing blocks (14) placed on the periphery of the bed (12) and, by heating the stack, so as to reach at least the melting point of the resin while leaving the film infusible and smooth, and by letting the gas or gases present in the stack escape via at least one opening (O) left in the enveloping film and then via at least one emerging channel (42) provided in the compacting plate (13) and/or in the bed (12) ad/or in the fixing blocks (14).

摘要： The invention relates to a method for producing a structural part (100, 150) including at least two flanges extending in intersecting planes, consisting of a composite thermoplastic material with a fibre reinforcement including at least two plies (11, 12, 13, 14) 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 (110), by welding along a forming generator; 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 (22) and a rigid die (21) 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.
摘要翻译：本发明涉及一种用于生产结构部件（100,150）的方法，所述结构部件（100,150）包括至少两个在相交平面中延伸的凸缘，所述凸缘由具有纤维增强材料的复合热塑性材料组成，所述纤维增强材料包括至少两层（11,12,13,14）所述纤维从一个凸缘延伸到另一个凸缘，其中所述方法包括：切割步骤，包括在纤维预先浸渍的织物和/或纤维网中切割所述至少两个层; 用于通过沿成形发生器焊接来组装帘布层以形成坯料（110）的悬垂成形步骤; 以及用于通过使所述坯料经受预定的温度和压力循环将所述坯料压实成所述部件的限定形状的固结步骤。本发明还涉及用于实现上述方法的设备。这种设备包括刚性冲头（22）和刚性模具（21），使得设备的关闭形成密封室，其中部件的形状形成在冲头和模具之间。
