Sizing composition for glass fibers, sized fiber glass products, and composites

摘要

The present invention relates to sizing compositions for glass fibers and glass fiber reinforced resins. In one embodiment, the present invention provides a sizing composition comprising at least one polyvinyl alcohol in an amount greater than about 65 weight percent of the sizing composition on a total solids basis, and at least one coupling agent in an amount greater than about 5 weight percent of the sizing composition on a total solids basis. Embodiments of the present invention also relate to fiber glass strands, glass fiber reinforced resin compositions, and methods for producing composites.
