Abstract: A pre-consolidated preform produced by knitting, the preform being intended for the manufacture of composite products, this preform being formed of a knit fabric including at least one polymeric material and at least one yarn of at least one reinforcing material, the knit fabric including a polymeric material P1 constituting less than 20% by volume of the knit fabric or of the pre-consolidated preform and serving as adhesive in the pre-consolidated preform.

Abstract: The object of the invention can be a method of manufacturing a product in the form of a sandwich comprising a core and outer layers. The outer layers may be composed of composite material comprising a fiber-reinforced polymeric matrix. The method uses an insert of heat-resistant material, for example silicone. The object of this invention can be to provide a method of manufacturing a sandwich that dissociates the choice of material of the core of the sandwich from the choice of the material of the outer layers.

Abstract: The object of the invention is a composite product that may include a knitted reinforcing structure, which has at least two skins, connected by links; the link density being between 1 link per 40 square stitches and one link per 10,000 square stitches. The invention also relates to the method for producing composite product obtained that may include between 55 and 85% by volume of polymeric material and between 15 and 45% by volume of reinforcing fibers.

Abstract: An aircraft wing comprising a movable flap which is able to move in rotation relative to a fixed central body, flexible piping and a rail for guiding the movable flap and the flexible piping. The flexible piping-runs along the rail and is secured to the rail close to a distal end of the rail. The wing comprises a structure for holding the flexible piping against or close to the guiding rail, which is borne by the fixed central body. The wing also comprises a housing for accommodating the flexible piping. The housing comprises a wall which is shaped such that the flexible piping coils up inside the housing, being pressed against the wall.

Abstract: The present disclosure relates to a process for manufacturing a product made of composite materials comprising areas with different functionalities from a knitted preform. The inventors have discovered that it is possible to knit a dry preform comprising areas of different composition and then to transform same by melting into a solid composite material comprising areas with different functionalities. By different functionality, it is possible to provide areas of different rigidity, areas of different abrasion resistance, and areas of different electrical conductivity or thermal conductivity, areas of different transparency.

Abstract: The present disclosure relates to a method for manufacturing a product comprising at least one zone made of polymeric material, in particular thermoplastic, from a dry knitted preform. The dry preform is produced in three dimensions, by weft knitting of a continuous piece corresponding to the shape of the finished product to be obtained. The preform is then consolidated by heating under pressure in a mold and then cooled. The method according to the invention is particularly advantageous because it makes it possible to obtain parts of polymeric material of controlled thickness; the finished products have no connection and require no assembly of different parts. The method does not cause any loss or drop of material. The method according to the invention is not accompanied by any release of toxic volatile elements at ambient temperature.
