  • Patent number: 7867566
    Abstract: A method for fabricating a reinforced matrix composite comprising the step of providing a composite preform having a fibrous structure and applying matrix material onto the preform in locations along the preform. A barrier material is applied to at least a portion of the coated preform to direct the flow of matrix material into the preform. The composite preform is heated to a temperature sufficient to render the matrix material viscous and insufficient to cure the matrix material. The pressure to the interior of the composite preform is reduced, while the pressure to the barrier material is increased. The temperature is maintained to flow the matrix material into the composite preform and to force gases from the fibrous structure. The composite preform is then cured and cooled to form a reinforced matrix composite having a low void content and a substantially uniform matrix distribution.

    Abstract: A method for fabricating a reinforced matrix composite comprising the step of providing a composite preform having a fibrous structure and applying matrix material onto the preform in locations along the preform. A barrier material is applied to at least a portion of the coated preform to direct the flow of matrix material into the preform. The composite preform is heated to a temperature sufficient to render the matrix material viscous and insufficient to cure the matrix material. The pressure to the interior of the composite preform is reduced, while the pressure to the barrier material is increased. The temperature is maintained to flow the matrix material into the composite preform and to force gases from the fibrous structure. The composite preform is then cured and cooled to form a reinforced matrix composite having a low void content and a substantially uniform matrix distribution.

  • Patent number: 6913058
    Abstract: The peripheral length (M) dimension of the outer peripheral surface of drums (35, 36) is set equal to the width (W) dimension of body ply materials (46A, 46B) used for tires or integral multiples thereof. The wrapping length (L) of the wrapper (40) in the direction of the length of the drum is set equal to the length dimension (L1) of the body ply materials (46A, 46B) used for tires. A ribbon (39) of predetermined width dimension in the form of a cord having a rubber covering applied thereto is produced. The ribbon (39) is spirally wound on the outer peripheral surface of the drums (35, 36) and the lateral edges of the ribbon are bonded together, thus producing the wrapper (40). The wrapper (40) is cut along a gentle curve which is substantially orthogonal to the direction of the length of the ribbon, thus providing the body ply materials (46A, 46B).

  • Publication number: 20040074591
    Abstract: An apparatus for applying weft yarns in a cross direction to warp yarns assembled on a beam in parallel aligned relationship and having an adhesive scrim thereon includes a supply roll of the warp yarns on such a beam which are fed downstream of the apparatus by first laying the warp yarns onto a transfer belt to reduce the tension in the yarns and controlling them for application of the weft yarns. A transfer belt and warp yarns are first folded between folding bars into a cylindrical configuration where they are formed around the perimeter of an elongated mandrel having a heated section at its upstream end and a cooling section at its downstream end. The adhesive scrim is softened as the warp yarns pass over the heated section of the mandrel and shortly thereafter, weft yarns are wrapped around the warp yarns and the supporting transfer belt within a rotating tube having a plurality of longitudinally and circumferentially spaced spools of weft yarn disposed on its outer surface.

  • Patent number: 6533882
    Abstract: In one general aspect, the invention involves applying a chemical treatment to fibers, such as reinforcing fibers suitable for making a composite article, so as to size and/or preimpregnate the fibers. The chemical treatment has a relatively low viscosity and is substantially solvent-free and non-radiation curable. Heat energy may be employed to lower the viscosity and improve the wetting ability of the applied treatment and/or to increase the molecular weight of, or otherwise cure, the treatment with essentially no generation of solvent vapor. The treated fibers are used to form a composite strand, which may be subsequently processed in-line or off-line into a composite article having fibers disposed in a polymeric matrix. Another general aspect relates to encased composite strands, in thread or pellet form, and to wire-coating methods and apparatus for making them. The strands are moldable into fiber-reinforced thermoplastic composite articles.

  • Publication number: 20020033222
    Abstract: Filamentous textile structures are produced from a quasi continuous planar nonwoven (1) by subjecting the nonwoven (1) to fluid-dynamic forces, namely in such a way that the nonwoven (1) is split up longitudinally into a plurality of parallel slivers (3) and the fiber structure of the nonwoven (1) is bonded in the slivers. For the treatment with fluid-dynamic forces, the nonwoven (1) is placed for example against a treatment template (10) which is structured in a strip-like manner by perforations (11) and elevations (12) and fine water, saturated steam or air jets (13) are directed against the nonwoven (1) and the template (10). The slivers produced during the treatment with the fluid-dynamic forces can be processed without any further treatment into a planar textile structures or they can be subjected to a further treatment prior to said processing in order to increase their strength.
