Abstract: A multi-compatible sizing composition that includes an epoxy resin emulsion, a silane coupling agent package, a non-ionic lubricant, and a crystalline polyol is provided. The epoxy resin desirably has an epoxy equivalent weight from 180-195. A preferred emulsifier is a modified polyethylene oxide-polypropylene oxide block copolymer. The silane coupling agent package includes an aminosilane and a vinyl silane coupling agent. The sizing composition may be used equally well with epoxy, unsaturated polyester, and vinylester thermosetting resins. Reinforcement fibers sized with the inventive sizing composition possess low friction on contact points, low fuzz, and reduced drag. Other performance characteristics such as in-plane shear and dynamic fatigue are also improved by the multi-compatible sizing composition. Fibers sized with the multi-compatible sizing composition may be used, for example, to form woven rovings and fabrics, in filament winding applications, and in pultrusion processes.

Abstract translation: 提供了包括环氧树脂乳液，硅烷偶联剂包装，非离子润滑剂和结晶多元醇的多相容尺寸组合物。 环氧树脂理想地具有180-195的环氧当量。 优选的乳化剂是改性聚环氧乙烷 - 聚环氧丙烷嵌段共聚物。 硅烷偶联剂包括氨基硅烷和乙烯基硅烷偶联剂。 施胶组合物可以与环氧树脂，不饱和聚酯和乙烯基酯热固性树脂同样好地使用。 用本发明的施胶组合物尺寸的增强纤维在接触点上具有低摩擦力，低绒毛和减少的阻力。 其他性能特征，如平面内剪切和动态疲劳也可通过多相容尺寸组合物得到改善。 可以使用通过多相容尺寸组合物尺寸的纤维，例如在长丝缠绕应用中和拉挤成型工艺中使用织造粗纱和织物。
