Definitions

  • the invention relates to an improvement made to reinforcements textiles used for the production of a composite material, i.e. resin-based articles (polyester or other), reinforced with a textile tablecloth reinforcement.
  • the frame which is the subject of the aforementioned patent consists of at least two layers of textile reinforcement properly say, arranged on either side of a central layer giving the thickness of said material and it is characterized in that said layer central consists of a tablecloth based on synthetic fibers, of title high unit and which received prior to their formatting tablecloth a treatment communicating to them an undulation or crimp permanent leading to the formation of a light, thick and airy.
  • the different layers are linked together by sewing / knitting.
  • the textile reinforcement layers arranged on either side of the central layer giving the thickness are advantageously consisting of fibrous mats possibly associated with other reinforcements textiles.
  • the reinforcements produced in accordance with the aforementioned patent are particularly suitable for use in the techniques of press molding, injection molding and vacuum molding.
  • connection different layers by sewing / knitting sometimes resulted in surface appearance defects, especially on the chain side formed by such links.
  • further processing in accordance with the invention consists, in a frame of the type which is the subject of the patent aforementioned French and which therefore comprises at least two layers of reinforcement textile arranged on either side of a central layer giving the thickness of said material, said layers being linked together by sewing / knitting, to be brought back, at least against one of the external faces of the complex, a veil of synthetic fibers, the bond of said veil being produced either by bonding outside the complex, or through seams connecting the different layers together.
  • the central ply is preferably based on synthetic fibers of high title and curly in a similar manner to the aforementioned patent, but may also be based on other coarse fibers, for example fibers vegetable.
  • This central tablecloth preferably has a weight of between 150 g / m2 and 400 g / m2. Indeed, for a weight less than 150 g / m2, the complex lack of dress and regularity, while a weight greater than 400 g / m2 leads to thick products which are not justified in the practice.
  • the thickness of this central ply is generally understood between 3 and about 8 mm.
  • the textile reinforcement layers placed on either side of the layer central are advantageously constituted by a glass mat, possibly reinforced by a textile grid, the weight of these layers being generally between 300 and 600 g / m2.
  • a veil of synthetic fibers having a grammage between 50 and 150 g / m2, synthetic fibers entering in the realization of such a veil being very thin, and generally having a titer between 1 and 7 dtex, i.e. much finer fibers than those used in the composition of the reinforcement itself.
  • Such fineness of the surface fibers makes it possible to have a very good homogeneity, favoring the distribution of the resin during molding. By elsewhere, these surface fibers prevent marking by the fibers coarse internal structure.
  • FIGS. 1 to 4 appended corresponding to four types of product produced according to the invention.
  • this basic structure is associated with the less against one of the external faces, a veil of synthetic fibers designated by reference (4).
  • This or these sails (4) can either be glued to outside the complex three-layer linked by sewing / knitting, either be reported against one or other of the external faces of the complex before they are not linked by sewing / knitting.
  • Figure 2 illustrates an embodiment in which the same polyester veil (4) is added to the outside of the complex (1,2,3) previously linked by sewing / knitting.
  • two sails (4) are associated on both sides of the complex, one placed against the tablecloth (3) being sewn, the other arranged against the tablecloth (2) being glued to the top seams.
  • Such a product makes it possible to obtain a composite material having an excellent surface finish on both sides of the final part.
