Problems solved by technology

In fact, this method does not allow the fabric to be under tension, so that wrinkles and / or puckering can form in or near non-extensible areas
Furthermore, this method of forming / compressing from films or bags does not allow for increased production rates for series in relation to the intended use
Therefore, according to the prior art there is no suitable method for the manufacture of such parts

Embodiment Construction

[0045] exist figure 1 Among them, according to an example of implementation, the part 100 that is the object of the invention has the shape of a half-shell comprising a bottom 110 and a flanged edge 120 . The profile 111 of the part 100 is continuous so that the part includes a non-developable area 121 with a triangular connection between the flanged edge 120 and the bottom 110, which is called a "corner fitting". The bottom is shown here as a plane. According to a better embodiment (not shown), the bottom can be formed according to a curved surface in the form of a double arc. Said part 100 consists of a laminated composite material comprising a plurality of plies comprising so-called continuous fibers 130 . So-called continuous fibers extend from one side of the part 100 to the other in a continuous fashion. According to a better embodiment, said fibers consist of reconstituted continuous fibers or monomeric continuous fibers formed of a group of fiber filaments, for exa...

Abstract

The invention relates to a forming and consolidating device for a textile preform (600) comprising impregnation with a thermoplastic polymer, a method carried out by said device and parts obtained by this method continuous fiber, said device comprising: i. a die (200) comprising a mold (210) comprising a mold cavity (220) corresponding to the shape of the part, said mold between the inlet plane and the bottom The space extends along the depth direction and is inserted into the mold chassis (230); ii The induction heating mechanism (241, 242) of the model (210) includes two inductors, and the two inductors extend to the model (210) Coils are formed in the cavities and each in a plane substantially parallel to the entry plane of the cavity (220) and between said entry plane and the bottom of the mould; iii cooling mechanism (235) of the cavity.

Description

technical field [0001] The invention relates to a device and a method for the compression-consolidation of parts made of composite materials having a thermoplastic matrix reinforced with continuous fibers, especially of natural origin. More particularly, the invention is suitable for the mass production of half-shell-shaped and non-developable composite parts with a thermoplastic matrix, said parts comprising 4 flanged edges along a closed contour, said edges being formed by The triangular connectors at the corners of the body are connected. Parts of this type are used in particular as housings or half-shells for telecommunication terminals such as mobile phones, personal digital assistants or personal tablet computers. Alternatively, but not limited to, the half-shells may be used as housings for electronic components and screen supports when assembled to the objects for which they are used, or possibly as additional protective casings capable of containing related objects. ...
