Patent number: 7094468Abstract: The present invention provides a sizing agent capable of imparting superior resin impregnation and adhesion with resin, and more particularly, a carbon fiber sizing agent that have satisfactory emulsification stability having stable process throughput and minimizes the changes over time in the sized carbon fibers. The carbon fiber sizing agent contains (A) a compound having at least one epoxy group per molecule, (B) an anionic surfactant having an ammonium ion as the counter ion, and (C) a nonionic surfactant wherein, the nonionic surfactant (C) is contained at 1/50 to ½ (weight ratio) relative to the anionic surfactant (B).Type: GrantFiled: May 24, 2002Date of Patent: August 22, 2006Assignee: Mitsubishi Rayon Co., Ltd.Inventors: Naoki Sugiura, Masato Taguchi, Tadayoshi Saito

Patent number: 7083855Abstract: A binder slurry for a continuous filament mat used in a phenolic pultrusion system comprising a phenolic compatible silane, a non-ionic surfactant, a defoamer, water, an organic acid and a bisphenol epoxy powdered resin having a thermally active dicyandiamide cross-linking resin. The binder slurry resin is unique in that the bisphenol epoxy powdered resin having a thermally active dicyandiamide cross-linking resin is compatable with presently available phenolic resins, and as such pultruded parts made have improved surface and mechanical properties as compared with traditional polyester type binder slurries which are not compatable with phenolic resins. Continuous filament mats made with the new binder slurry also may also be made into epoxy prepreg that can be used to make composite parts.Type: GrantFiled: March 7, 2003Date of Patent: August 1, 2006Assignee: Owens Corning Fiberglass Technology, Inc.Inventors: Adrian C. Lane, Jeffrey L. Antle
