| 摘要 |
An aqueous glass fiber sizing composition is provided which provides high strength and wet-out to composites prepared using glass fibers having the sizing composition of the present invention applied thereto. When used to reinforce a thermosetting polymeric material, the glass fibers sized with this composition provide a composite useful in making pultrusion profiles having high compressive, shear and flexural strengths. The composition includes a nonionic urethane-modified epoxy thermosetting copolymer, a water-soluble, dispersible or emulsifiable epoxy film-forming polymer; an emulsifying agent; and organo-functional silane coupling agent; a fiber lubricant; and water in an amount sufficient for application of the sizing composition to at least one glass fiber. |
