  • Composite materials and products made therefrom
    Patent number: 6540867
    Abstract: An article made up of (1) a composite having a polyurethane matrix including fibrous or particulate reinforcement, the polyurethane matrix being formed in situ about the reinforcement by reaction of polyurethane forming components at a temperature below the melting point of the reinforcement and (2) a polymeric film bound to at least one surface of the composite, the film being bound to the composite by adhesion to the polyurethane matrix which emerges or is enhanced as the matrix is formed in situ.
    Type: Grant
