Patent number: 8802232Abstract: A powder coated roving material for making structural parts is provided. The powder coated roving includes a bundle of fibers at least substantially coated with a powder coating material. The bundle is formed of a plurality of inner fibers and a plurality of outer fibers surrounding the inner fibers. The size composition maintains the fibers in a bundled orientation during processing and releases the fibers during molding. The size composition includes an epoxy resin emulsion containing at least one surfactant and a solid epoxy resin having an epoxy equivalent weight from about 450 to about 950, at least one epoxy silane coupling agent, at least one non-ionic lubricant, at least one cationic lubricant, and at least one organic acid. In addition, the size composition may have an acetone solubility from about 30% to about 75%. A method of making a composite roving is also provided.Type: GrantFiled: January 15, 2010Date of Patent: August 12, 2014Assignee: OCV Intellectual Capital, LLCInventors: Leonard J. Adzima, Michael A.

Publication number: 20120034441Abstract: A wet fiber based composition that includes wet glass fibers, a water dispersible polymeric resin, and gypsum is provided. Components including melamine formaldehyde, a filler material, coupling agents, acetic acid, an accelerator, and/or a hardener may also be added to the composition. The gypsum may be a-gypsum, B-gypsum, or combinations thereof. The wet glass fibers are wet chopped glass fibers or a wet continuous roving. The combination of the wet glass fibers, the water dispersible polymeric resin, and the gypsum have a synergistic effect that creates a composite product that is water resistant, fire resistant, and has improved mechanical properties. In one exemplary embodiment, the wet fiber based composition is used to form a gypsum board that can be molded into various composite products. In other exemplary embodiments, thin multi-ply gypsum boards may be formed by alternately layering glass mats with layers of a gypsum/polymer slurry.Type: ApplicationFiled: April 12, 2006Publication date: February 9, 2012Inventors: Leonard Adzima, Paul R. Krumlauf, William G. Hager, Jocelyn M. Seng, Ralph D. McGrath, Kevin S. Guigley, Yadollah Delaviz, Fatemeh Nassreen Olang, Yihsien H. Teng

Publication number: 20110305904Abstract: A sizing composition that permits in-line chopping and drying of reinforcement fibers for reinforcing thermoset resins is provided. The size composition includes at least one coupling agent and one or more blocked polyurethane film forming agents. The blocking agent preferably de-blocks at a temperature that permits simultaneous or nearly simultaneous de-blocking and curing of the polyurethane film former. The sized fiber strands may be chopped to form chopped strand segments and dried in a fluidized bed oven, such as a Cratec® drying oven, in-line. The chopped fiber strands may then be used in a bulk molding compound and molded into a reinforced composite article. Chopping the glass fibers in-line lowers the manufacturing costs for products produced from the sized fiber bundles. Further, because the reinforcement fibers can be chopped and dried at a much faster rate with the inventive size composition compared to conventional off-line chopping processes, productivity is increased.Type: ApplicationFiled: May 11, 2011Publication date: December 15, 2011Applicant: OCV INTELLECTUAL CAPITAL, LLCInventors: Eric L. Vickery, David M. Boies, William G. Hager
