Abstract: A process of making a molded laminar structure from a reinforced fibrous mat impregnated with an uncured thermal setting resinous binder wherein the mat is compressed and molded, the binder cured to form a shell, a covering secured to one surface of the shell to form a laminar structure, and trimming the laminar structure to predetermined dimensions.

Abstract: A glass-fiber-containing nonwoven polymer web is prepared by providing a nonwoven polymer web, applying a layer of glass fibers onto the nonwoven polymer web, and encapsulating the glass fibers into the nonwoven polymer web utilizing heat and pressure. Alternatively, a glass-fiber-containing polymer web is prepared by providing a first nonwoven polymer web, applying a layer of glass fibers onto the first nonwoven polymer web, superposing over the layer of glass fibers a second nonwoven polymer web, and laminating together the assemblage to encapsulate the glass fibers.

Abstract: A glass fiber containing polymer sheet is prepared by providing a first polymer sheet, applying a layer of glass fibers onto the first polymer sheet, superposing over the layer of glass fibers a second polymer sheet, and laminating together the assemblage.

Abstract: A glass fiber containing polymer sheet is prepared by providing a non-woven carrier web, superposing an adhesion film over the carrier web, applying a layer of glass fibers onto the adhesion film, and laminating together the assemblage.

Abstract: An acoustical panel comprises a compressed and cured mass of binder impregnated randomly oriented and interentangled fibrous glass bundles. The acoustical panel surprisingly is characterized by high sound absorption coefficients at low frequencies.

Abstract: A method for hardening a portion of a fiberglass product and fibrous product with a hardened portion are disclosed. A heated thermoplastic resinous material is applied to a fibrous product. The thermoplastic resinous material has a viscosity that allows the resin to permeate the fibrous product. THe resinous material is only applied to the portion of the fibrous product to be hardened. The resinous material is then cooled whereby the resinous material solidifies and the portion of the fibrous product permeated with the resins is substantially hardened.

Abstract: A fibrous product is disclosed having a first layer of high density substantially rigid fibrous material. The first layer has a first surface and a second surface. The first layer defines an edge around the outer periphery of the first and second surfaces. A second layer of fibrous material is positioned adjacent the second surface of the first layer. The second layer is at least twice as thick as the first layer and the second layer has less than one-half the density and rigidity of the first layer. The second layer defines an edge around the outer periphery of the second layer. The edge of the second layer is substantially in alignment with the edge of the first layer. A covering of decorative fabric material is positioned at least on the first surface of the first layer and along the edges of the first and second layers.

Abstract: A method and apparatus for impregnating a fibrous web is disclosed having a conveyor for advancing the fibrous web. The fibrous web having a first surface and a second surface. An applicator is provided for applying a foamed binder to the first surface of the fibrous web and the foamed binder seals the first surface of the web. A vacuum chamber is positioned adjacent the second surface of the web. The vacuum chamber contains a narrow slot adjacent the second surface of the web for applying a vacuum to the web. The vacuum acts upon the web to reduce the thickness of the web and to draw the foamed binder material into the web to impregnate the web.
