  • Patent number: 11161950
    Abstract: The present invention relates to a self-adhesive article comprising a non-random fabric of bundles of carbon fibres and a thermosetting epoxy resin composition. The self-adhesive article exhibits high surface adhesion and excellent dimensional stability at room temperature. The self-adhesive article is ideally suited to reinforce structural components, particularly vehicles or ancillary vehicle components. The structural components reinforced by the self-adhesive article exhibit improved impact and torsional strength.

  • Publication number: 20140042706
    Abstract: A continuous filament non-woven web is disclosed, wherein filaments of the web include an expandable thermoplastic material. Mattings fabricated from the continuous filament non-woven web are also disclosed. The web or matting can be used in sealing applications as it can be cut into desired dimensions and inserted into a cavity. The web or matting allows for introduction and drainage of further fluids in and from the cavity. The extendable thermoplastic material can be activated and foamed to fill a part of or the entire cavity. The sealing can prevent air, water or noise from intruding into the cavity and a space behind that cavity.

  • Patent number: 8163380
    Abstract: Compositions for damping the vibration of mechanical components, such as those used in vehicles, are disclosed and described. The compositions comprise a water-based polymer resin and a drying control agent. The drying control agent minimizes the occurrence of cracks and swelling in the damping coating films when the coating films are baked and dried.

  • Publication number: 20090001758
    Abstract: An expandable insert and a method of making the same are disclosed. An expandable insert may generally include an expandable body that extends along a hollow structure, and has a continuous outer periphery. A passageway extends through the outer periphery that allows fluid communication therethrough. The expandable insert is operable to be expanded to fill a cross-section of the hollow structure. A method of forming an expandable insert may generally include forming an expandable body, including forming a continuous outer periphery and a passageway extending through the outer periphery to allow fluid communication therethrough. The method may further include expanding the elongated body to fill a cross-section of the hollow structure.

  • Publication number: 20070281095
    Abstract: A system includes a first layer of a first polymeric material being visco-elastic when solidified. The first polymeric material covers a first portion of a substrate. A second layer of a second polymeric material (being stiff when solidified) covers at least a portion of the first layer and at least a second portion of the substrate. Additionally, a method includes applying a layer of first polymeric material to a first portion of a substrate. The first polymeric material is visco-elastic when solidified. Additionally, a layer of a second polymeric material (being stiff when solidified) is applied to the first polymeric material and a second portion of the substrate. The first polymeric material is constrained between the second polymeric material and the substrate. Both of the first polymeric material and the second polymeric material are dispensed in fluid form from a bulk source of fluid material.
