Fibers, such as those derived from cellulose, as used in the manufacture of paper, may be used along with long fibers, as previously indicated, and as are well known to those skilled in the art.

  • Foamed films or films which are used in accordance with the invention as starting carrier materials are flexible and have an open-cell structure. This is according to the invention to pay attention to the flexibility and deformability, as it exists in the tissues, knitted fabrics, mats, nonwovens and the like.
  • Synthetic leathers may also be classified into two general categories, coated fabrics and poromerics, within the scope of the invention.
  • Synthetic leathers which are Poromerics, are made to be as leather-like as possible in terms of breathability and water vapor permeability as well as machinability, machine compatibility and other properties.
  • Synthetic leathers, which are coated fabrics have a balance of physical properties and economic considerations, such as porometrics.
  • the coating is either a vinyl polymer or a polyurethane.
  • Vinyl coatings can be either solid or expanded vinyl polymers having internal air bubbles, such as those typically found in closed cell foams. Because of this structure, they usually have a non-porous front surface or appearance. This construction leads to poor breathability and water vapor permeability. However, because the interior or the back are porous, these materials can be used for the purposes of the invention by applying the curable thixotropic material and one or more modifiers to the back surface thereof.

Abstract

L'invention concerne un matériau composite flexible qui comprend une première couche flexible, la couche de base, issue du groupe composé de fibres, de tissus, de tissus à mailles, de non-tissés, de mats, ou autre, éventuellement une autre couche flexible conforme à la première couche, une autre couche flexible encore à base d'un matériau contenant des fibres de carbone et d'une résine imprégnant la couche flexible, qui maintient la flexibilité des couches. L'invention concerne également un procédé pour produire le matériau composite qui comprend les étapes suivantes: réunir une couche de base flexible inférieure avec une couche flexible à base de fibres de carbone située dessus, imprégner les deux couches d'une composition silicone qui comprend une résine silicone, faire durcir la résine silicone, tout en maintenant la flexibilité des couches, ainsi que l'utilisation desdites couches.
