  • Patent number: 3957556
    Abstract: A method and apparatus for producing a sheet molding composite are provided. The sheet molding composite consists of two outer sheets of plastic material between which is sandwiched a moldable material or compound containing fiber-reinforced resin. The resin-containing material is maintained in a deformable, flexible state until it is placed in a mold and subjected to heat, at which time it is cured in the shape of the final molded product. The molding composite is made by depositing a layer of a pre-blended resin-containing material on the upper surface of one of the sheets of plastic material and by then depositing a layer of randomly disposed glass fibers onto this first layer. A second layer of preblended resin-containing material from the same source is also deposited on an upper surface of a second of the plastic sheets.
