The outer vinyl layers are also heated to a suitable temperature for bonding and all layers are brought together in a nip which applies pressure sufficient to bond the vinyls layers with the scrim.

    Abstract: A laminate for use as a headliner comprises a core having an adhesive layer provided adjacent opposing sides thereof. Basalt fiber structural reinforcement layers are provided adjacent each adhesive layer. A scrim layer is provided next to one reinforcement layer while a film barrier and covering are provided adjacent the other reinforcement layer. A method for manufacturing the laminate comprises the steps of providing a core, providing basalt fiber reinforcement layers adjacent opposing sides of the core, providing adhesive layers between opposing sides of the core and the reinforcement layers, applying a scrim layer to one reinforcement layer and a film barrier and covering to the other reinforcement layer to complete the laminate. According to a method for recycling a laminate, laminate material formed of composite materials including reinforcement fibers that have a melting point above the incineration point of the other composite materials is provided.

    Abstract: A structural reinforcement layer for use in a laminate for a vehicle headliner comprises at least one of carbon fibers and natural fibers. A thermoplastic binder may adhere the fibers to one another. A method for manufacturing a laminate comprising a the structural reinforcement layer comprises the steps of providing a core, providing a first reinforcement layer containing carbon fibers adjacent one of opposing sides of the core, providing adhesive layers on each of the opposing sides of the core, applying a barrier film and covering to the first reinforcement layer to the first reinforcement layer. Applying a scrim mat comprising a reinforcement layer, a barrier film and a scrim layer to the other of the opposing sides of the core to complete the laminate. According to a method for recycling a laminate, laminate material formed of composite materials including carbon fibers that have a melting and/or degradation point above the incineration point of the other composite materials is provided.

  • Publication number: 20040235377
    Abstract: A laminate for use as a headliner for an automobile comprises a core that is a mixture of basalt fibers and polypropylene binder. A scrim layer is provided adjacent a first side of the core. An adhesive layer and a covering are provided adjacent a second side of the core. The laminate can be manufactured by heating the core, providing a scrim layer adjacent the first side of the core and providing an adhesive layer and a covering adjacent the second side of the core to complete the laminate. A method for recycling a laminate comprises the steps of providing a laminate material formed of composite materials including reinforcement fibers that have a higher melting point than the incineration point of the other composite materials and heating the laminate to a temperature below the melting point of the basalt and above the incineration point of the other composite materials to reduce the other composite materials to ash without melting the basalt.

  • Patent number: 6818282
    Abstract: A laminated fabric floor product having an encapsulated fabric scrim within a vinyl resilient flooring structure. The laminated fabric floor product structure includes a PVC calendered base, a first hot melt film, a fabric, a second hot melt film, a calendered clear film, and a high performance coating. Traditional foamed and non-foamed substrates used in the flooring industry can be used in addition to the calendered base. All types of fabrics and scrims can be encapsulated. The fabrics can be both woven and non-woven types. Open scrims can be used with base layers that are printed or have a visual pattern so that design features and colors can be seen through the open areas of the scrim. The fabric layer can be printed with a design pattern and adhered to the base layer or substrate by the first hot melt adhesive film layer. The clear layer is adhered to the fabric layer by the second hot melt adhesive layer.

  • Publication number: 20040219846
    Abstract: A composite sheet biasable into a tubular shape to form a sleeve for isolating or protecting elongated items is disclosed. The sheet has a reflective surface formed by a metal foil layer overlying a flexible polymer layer having a metalized surface. A biasable polymer netting layer is positioned overlying the flexible layer opposite the metalized surface. The netting layer is formed of elongated members that define interstices. A damping layer of non-woven material is positioned adjacent to the netting layer. An adhesive layer is positioned between the flexible layer and the netting layer to bond the netting layer and the damping layer to the flexible layer. Biasing is effected by the elongated members of the netting layer which are stiffer in the circumferential direction around the sleeve to provide radial stiffness.

  • Patent number: 6787486
    Abstract: A backerboard sheet is for moist areas and includes a core having opposing first and second major surfaces, at least one moisture-resistant face layer on at least one of the first and second major surfaces of the core; and wherein the core includes aerated concrete. The provision of aerated concrete for the core provides many key advantages over conventional backerboard sheets, such as gypsum greenboard or cementitious backerboard, for example. The at least one moisture-resistant face layer may include fibers, such as arranged in a woven mesh. The fibers may include at least one of glass, plastic, and metal. In addition, the at least one moisture-resistant face layer may further include a moisture-resistant material incorporating the fibers, such as a suitable resin, for example.
