Abstract
Abstract Glass fibers coated with a size composition comprising gamma-aminopropyltriethoxysilane and an alkoxysilane are disclosed. When a glass fiber size composition of this invention is employed on glass fibers incorporated into plastics reinforced by the incorporation of the fibers, the resulting product exhibits improved strength properties.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
38 words
A glass fiber at least a portion of the surface of which is in contact with a residue produced by removing water from an aqueous composition comprising gamma-aminopropyltriethoxysilane and another alkoxysilane selected from methyltrimethoxysilane, phenyltrimethoxysilane, methylphenyldimethoxysilane and diphenyldimethoxysilane.
Claim 2
Dependent Claim
38 words
A glass fiber at least a portion of the surface of which is in contact with a residue produced by removing water from an aqueous composition comprising gamma-aminopropyltriethoxysilane and another alkoxysilane selected from methyltrimethoxysilane, phenyltrimethoxysilane, methylphenyldimethoxysilane and diphenyldimethoxysilane.
Claim 3
Dependent Claim
33 words
The glass fiber of claim 1 in which said gamma-aminopropyltriethoxysilane is employed in an amount within the range of from about 0.1 to about 1 percent by weight of said aqueous size composition.
Claim 4
Dependent Claim
33 words
The glass fiber of claim 1 in which said alkoxysilane is employed in an amount within the range of from about 0.1 to about 1 percent by weight of said aqueous size composition.
Claim 5
