Sized Glass Fibers And Reinforced Polymers Containing Same
US Patent:
4637956, Jan 20, 1987
Filed:
Mar 29, 1985
Appl. No.:
6/717758
Inventors:
Balbhadra Das - Pittsburgh PA
Chester S. Temple - McKees Rocks PA
Carl A. Melle - Allison Park PA
Chester S. Temple - McKees Rocks PA
Carl A. Melle - Allison Park PA
Assignee:
PPG Industries, Inc. - Pittsburgh PA
International Classification:
B32B 900, D02G 300
US Classification:
428391
Abstract:
Strands of chemically treated glass fibers of the present invention result in fiber reinforced polar thermosetting and thermoplastic polymers having good strength properties. The chemically treated glass fibers are treated with the an aqueous chemical treating composition having an epoxy polyurethane copolymer or a polyepoxide resin with blocked polyisocyanate functionality, and at least one or more organo coupling agents. The epoxy polyurethane copolymer or epoxy with polyisocyanate functionality can be chain extended with organic polyols. The blocked polyisocyanates can be either partially or fully blocked. Also the aqueous chemical treating composition can have one or more cationic and/or nonionic fiber lubricants, epoxy polyvinyl acetate copolymer in conjunction with an ethylene vinyl acetate copolymer or an epoxy polymer and mixtures of the fiber lubricant with the polymeric materials.
