Definitions

  • the present invention relates to the technical sector of woven meshes.
  • the present invention consists of low weight woven mesh (known in English as scrim) consisting of fiberglass threads, used as a backing for core materials (known in English as core materials) used in turn in composite materials of type structure sandwich (known in English as sandwich-structured composite materials), and characterized by the use of higher-grade fiberglass yarn (i.e., linear weight) to provide greater mechanical resistance per wire, and for improved resistance to the rupture in both directions, but especially in the transverse or plot, which directly contributes to the problem of scrim tears during handling by the users of the flexible panel.
  • scrim low weight woven mesh
  • core materials known in English as core materials
  • composite materials of type structure sandwich known in English as sandwich-structured composite materials
  • Composite sandwich structure materials are an element commonly used in mobile structures and / or components to reduce the amount of energy required to operate or move. Examples of this type are found in airplanes and maritime vessels, where components made of composite materials allow to alleviate the entire structure and reduce fuel consumption. There is also the case of wind turbine blades, which can be considered a large structure made of composite materials, thanks to which in recent years lengths greater than the wingspan of commercial aircraft have been achieved, maintaining a light weight that allows the wind turbine to rotate at a wider range of wind speeds, which includes low speeds.
  • the core material (1), or core material as it is called in English is the main component of composite sandwich structure materials (4), or sandwich-structured composite material as it is known in English.
  • These materials are on the market in the form of rigid or flexible panels, and the most common options of materials are balsa wood, and foamed PET and PVC.
  • these flexible panels are in dimensions of 61 Omm x 1, 220mm (approximately 24 ”x 48”) and the thickness varies according to the user's needs, usually in a range of 6 to 50 mm (1 ⁇ 2 ”to 2” ).
  • a new scrim mesh design (5) is presented to solve a recurring problem reported by the end users of the flexible panels (7), where they indicate that the mesh tends to break during the usual handling of the panel throughout the production process of the sandwich structure pieces (4). This situation has been reported particularly in panels with thicknesses above 38 mm (1-1 ⁇ 2 ”), which are of higher consumption.
  • the composite material (4) is obtained.
  • a standard scrim mesh (5) manufactured by ios is used by a textile process, and is composed of continuous fiberglass filament yarns and covered by a polymeric sizing that allows optimum lamination rigid core material panel (1).
  • the general specifications of this mesh appear in table 1.
  • the glue that is used for the lamination of the mesh (5) is of a similar nature and compatible with the non-polymeric sizing it carries, and its interaction with the mesh (5 ) grants tear resistance between mesh (5) and core material (1) necessary for the flexible panel (7) to resist the handling to which it is subjected in subsequent processes such as the preparation of the kit of parts that will be placed in the mold Infusion

Abstract

La présente invention concerne un nouveu modèle de maillage scrim (5) qui présente une construction d'armure simple (également connue comme armure taffetas) identique à la norme scrim. Comme n'importe quel tissu fabriqué sur un métier à tisser, il est nécessaire que les fils de chaîne (9) qui vont dans la direction de la production du métier à tisser, soient entrelacés avec les fils de trame (10) qui s'insèrent transversalement dans la foule créée par le métier à tisser. La différence dans le nouveau scrim repose sur l'utilisation de fils en fibre de verre d'un titrage supérieur (c'est-à-dire, poids linéaire) pour conférer une résistance mécanique plus importante par fil, mais avec une réduction de la densité du tissu pour qu'il n'y ait pas une augmentation significative du poids.
