    Filed: September 4, 1984
    Date of Patent: November 4, 1986
    Assignee: Monsanto Company
    Inventors: James S. Holtrop, Richard P. Maurer
  • Method of making a thermoformable laminate structure
    Patent number: 4608104
    Abstract: A twin-sheet thermoformable laminate structure is provided which has two layers of foamed thermoplastic material. A coating of a fabric impregnated with an acrylic resin having a softening temperature greater than 75.degree. C. is applied to at least the outer surface of each layer of thermoplastic material.
    Type: Grant
    Filed: July 13, 1985

  • Thermoformable polymeric foam headliners
    Patent number: 4600621
    Abstract: Thermoformable laminate structure with a retroflexed margin comprises at least one sheet of thermoplastic foam having a polymer-impregnated cloth adhered to at least one side thereof. Such laminate structure is useful in an automobile headliner assembly where hidden clips engage the retroflexed margin to hold the headliner proximate the roof without the need for garnish molding.

  • Thermoforming of styrenic foam laminates
    Patent number: 4595551
    Abstract: Thermoforming of styrenic foam laminates having at least one outer layer of polyurethane foam having an outer facing of decorative fabric. Prior to thermoforming the laminate is heated to at least the thermoforming temperature of the styrenic foam but to a temperature such that the decorative fabric is not degraded. The thermoforming process is useful in making automobile headliners.

  • Laminate structure with improved acoustical absorption
    Patent number: 4557970
    Abstract: A laminate structure with improved acoustical absorption is provided which has a first and a third layer of foamed thermoplastic material and a second layer, intermediate the first and third layers, which is a material having acoustical properties different from the properties of the material of the first and third layers. A portion of the surface area of each layer is adhesively bonded to the adjacent layer. A sheet of paper or fabric is adhesively bonded to at least the outer surfaces of the first and third layers.
