Abstract: A tooling for manufacturing by stamping parts made of thermoplastic material from a blank of the material. A hollow die is delimited by a bottom, side walls and an opening opposite the bottom, and a raised punch designed to cooperate with the die via the opening. The tooling includes at least one mobile element to cooperate with at least one recess placed in the bottom and/or side walls of the die, the recess allowing the passage of one part of the blank that is to be bent using the mobile element.

Abstract: This invention relates to tooling (1) for manufacturing by means of stamping parts made of thermoplastic material from a blank of the said material, comprising a hollow die (2) delimited by a bottom (20), side walls (21a, 21b, 21c) and an opening (22) opposite the bottom, and a raised punch (3) designed to cooperate with the die via the opening (22). The tooling comprises at least one mobile element (4) adapted to cooperate with at least one recess (23) placed in the bottom and/or side walls of the to die, the recess allowing the passage of one part of the blank that is to be bent using the mobile element.

Abstract: A perforated skin consisting of at least one layer (N1-N3) of substantially rectilinear fibers associated with a resin and whose perforations define a regular repeated pattern (a, b, c), characterized in that the perforations affect at least 25% of the skin and in that, at least in a major part of the perforated skin, fibers (C1-C3) of the layer(s) (N1-N3) are uninterrupted by the perforations (P1-P3).

Abstract: A method for production of discontinuous elements, such as thrust-reverser cascade vanes, from a continuous premix. The premix (8), containing at least one layer of unidirectional continuous fibres (11) and a filler (9), is arranged in the large dimension of the elements (X-X1). The semi-finished product thus obtained is made up of parts (12a-12c) which will provide the elements and sheets of material (13a,13b) which will be subsequently removed.

Abstract: Structural tubular element (1) made of resistant fibers coated with hardenable resin and intended to form a part of a structure.According to the invention, this tubular element is characterized in that it comprises an inner axial wall (4), also made of resistant fibers coated with hardenable resin, forming integral part with said element and extending over the whole length thereof and in that, at the ends (3) of said element (1), portions (4A) of said axial wall (4) are accessible to form zones of fixation of said element to other parts of said structure.Production of structural parts, particularly in the aeronautical and spatial domains.

Abstract: Machine intended for cutting out transversely, along a straight or broken, oblique or right-angled cutting line, a band material adapted to be fed parallel to its length.This machine has in combination, a device to unwind the band at constant linear speed from a reel and a second device to, firstly, advance the unwound band at constant linear speed from a fixed plane support which extends at least from the second device into proximity of the cutting system, and secondly, permit an edge of the band to be applied against a lateral edge guide. Use of this machine includes cutting of pieces from flexible compound material.
