Claims14
A glass fiber sizing composition comprising at least one diol-organosilane and at least one triol-organosilane
- wherein said triol-organosilane is the hydrozylate of a triester organosilane of the formula R1—Si(OR2)3 wherein R1 is selected from a phenyl group or a saturated or unsaturated alkyl group having from 1 to 10 carbon atoms, optionally substituted with a halide, methacryloxy, cycloalkylepoxy, epoxy ester, mercapto, amino, ureido or carbamate moiety;
- and R2 is selected from a methyl, ethyl, 2-methoxy-ethyl, isopropyl, n-propyl or n-butyl moiety;
- and
- wherein said diol-organosilane is the hydrozylate of a diester-organosilane of the formula R3—Si(CH3)(OR4)2 wherein R3 is selected from a phenyl group or a saturated or unsaturated alkyl group having from 1 to 10 carbon atoms, optionally substituted with a halide, methacryloxy, cycloalkylepoxy, epoxy ester, mercapto, amino, ureido or carbamate moiety;
- and R4 is selected from a methyl, ethyl, 2-methoxy-ethyl, isopropyl, n-propyl or n-butyl moiety.
A glass fiber reinforced composite comprising an epoxy matrix and glass fibers coated with a sizing composition containing a triol-organosilane hydrozylate of a triester-organosilane of the formula R1—Si(OR2)3 and a diol-organosilane hydrozylate of a diester-organosilane of the formula R3—Si(CH3)(OR4)2, wherein R1 and R3 are independently selected from a phenyl group or a saturated or unsaturated alkyl group having from 1 to 10 carbon atoms, optionally substituted with a halide, methacryloxy, cycloalkylepoxy, epoxy ester, mercapto, amino, ureido or carbamate moiety, and R2 and R4 are independently selected from a methyl, ethyl, 2-methoxy-ethyl, isopropyl, n-propyl or n-butyl moiety.
