  • Sheet molding compound having improved characteristics
    Patent number: 7268092
    Abstract: A composite part made from a sheet molding compound is disclosed as having improved characteristics over traditional sheet molding compound composite parts. The fibrous material is introduced as a veil layer adjacent a paste layer, the veil flows well during the molding process. The improved flow and surface characteristics of a composite part are attributed to the elongation of the veil during molding and to the improved filling capabilities.
    Type: Grant

  • Sizing for glass fibers having low nonionic and cationic lubricant content
    Patent number: 6228281
    Abstract: A sizing composition for coating glass and carbon fibers. The composition comprises low concentrations of a cationic and nonionic lubricant, a film-forming polymer, and preferably a coupling agent and a hydrolyzing agent. Use of the sizing composition reduces fuzz development, increases wettability, and improves roving package stability.

  • Size compositions for glass fibers
    Patent number: 4683254
    Abstract: An aqueous size composition has been developed for glass fibers produced for molded products having appearance surfaces known as Class A surfaces. The size contains a cure stable polyester emulsion and a static insensitive lubricant system. The resulting coated glass fibers are especially useful in improving processability and product uniformity of SMC applications.
