The present invention relates to amino acid-containing sizing compositions for glass fibers, to glass fibers at least partially coated with such sizing compositions, to a variety of fiber glass products at least partially coated with such sizing compositions, and to composite materials comprising glass fibers at least partially coated with such sizing compositions. In one non-limiting embodiments, a sizing composition for glass fibers comprises an amino acid, a protein, or a hydrolyzed protein. A sizing composition for glass fibers, in another non-limiting embodiment, comprises an amino acid, a protein, or a hydrolyzed protein, at least one film-former, and at least one silane. |
