  • Publication number: 20190070802
    Abstract: A textile reinforcement that can be used for the creation of composite components by pultrusion, including a reinforcing layer having lengths of fiberglass oriented randomly and coated in a polyester binder. The reinforcing layer includes at least one reinforcement layer formed of fibers structured as a weave or as a mesh, or as longitudinal and transverse filaments. The reinforcing layer includes at least one thickness layer, adjacent to the reinforcement layer, and based on the lengths of fiberglass oriented randomly and coated in a polyester binder. At least one first surface layer as a web of fibers forms a first external face of the textile reinforcement. A second external face of the textile reinforcement is formed by the reinforcement layer or by a second surface layer as a web of fibers. The polyester binder binds the layers of the textile reinforcement together.

  • Publication number: 20170326834
    Abstract: Textile reinforcement that can be used for the production of composite parts by pultrusion, including a central layer made from glass fibre segments and polyester, and in which, in the central layer, the glass fibre segments are enrobed with polyester, the central layer including a central reinforcement core surrounded by the glass fibre segments enrobed with polyester, at least one fibre-web surface layer forming one of the external faces of the textile reinforcement.

  • Publication number: 20140147643
    Abstract: A thermoformable lap (1) includes a first web (3) and a second web (4) made of linking fibres (3a, 4a) made of a first thermoreactivatable material having a first reactivation temperature. An intermediate layer (2) is arranged between the first web (3) and the second web (4), and includes reinforcement fibres (2a) and granules (2b) of a second thermoreactivatable material having a second reactivation temperature that is higher than the first reactivation temperature. Certain sections (3b, 4b) of linking fibres of the first and second webs (3, 4) penetrate into the intermediate layer (2) and partially adhere to one another and to the reinforcement fibres (2a) of the intermediate layer (2), ensuring the cohesion of the assembly. Such a lap can be manufactured at a lower cost and at high speed, and can be used for the production of parts by heat moulding.

  • Publication number: 20120148790
    Abstract: A reinforcement layer (2) is based on parallel rovings (2a) of continuous glass strands, and one or two binding layers (3) consisting of portions of fibers having a heat-meltable surface. The assembly is consolidated by penetrating fiber portions (3b) that penetrate into the heat-meltable surface, these penetrating over a part of their length into the reinforcement layer (2) and adhering to the continuous glass strands of the rovings (2a).

  • Publication number: 20120148815
    Abstract: A core includes a thick, well-ventilated inner layer (2) made of fragmented slivers of continuous glass fibers (2a), the inner layer (2) being covered with two outer layers (3, 4) that consist of fiber segments having a hot-melt surface. The assembly is secured by penetrating fiber segments (3b, 4b) having a hot-melt surface, the segments penetrating, along part of the length thereof, into the inner layer (2) and adhering to the continuous glass fibers (2a).

  • Publication number: 20110151231
    Abstract: A textile armature that can be used for making composite materials or parts includes a central layer containing fiber segments of a first type of synthetic material previously submitted, before shaping it into a layer, to a process imparting a permanent crimp; outer layers including a mixture of segments of chemical fibers previously submitted to a process imparting a permanent crimping, and of segments of reinforcing fibers, at least some of the segments of chemical fibers of the outer layers penetrate along a portion of their length into the central layer. First segments of chemical fibers of the outer layers are bonded at least partially between them and to the other fiber segments of the textile armature.

  • Patent number: 5175042
    Abstract: Textile composite comprising at least two superposed nonwoven fibrous sheets (1, 2), Sheet (2) based on flexible synthetic fibers and the other sheet (1) based on inorganic fibers. Bonding of the sheets is obtained by means of a minor part (2a) of the synthetic fibers which are implanted into the thickness of the sheet (1).In the sheet (1), the fibers are oriented substantially parallel to the surface and form a relatively dense assembly, the sheet (1) being subjected, before its combination with the sheet (2), to a treatment producing fine perforations in its thickness, inside which perforations are preferably implanted the synthetic fibers (2a) which bond the sheets (1, 2) together.
