Patent number: 5026410Abstract: A method for impregnating a strand of filaments during the strand manufacture with thermoplastic or thermoset polymer powder particles is disclosed. The method includes the steps of forming a strand of filaments, keeping the filaments separate, impregnating the filaments with an aqueous slurry containing the powder particles, and drying the filaments to remove the water and produce a strand impregnated with powder particles. The powder particles are present on the strand in an amount of between about 5 to 50 weight percent based on the weight of the impregnated strand. Glass fibers coated with the slurry according to the process of this invention are suitable for impregnation with thermoplastic powders.Type: GrantFiled: November 9, 1988Date of Patent: June 25, 1991Assignee: Owens-Corning Fiberglas CorporationInventors: Jean-Claude Pollet, Gary L. Williams, Gordon P. Armstrong, Martin C. Flautt
