Claim 2
Dependent Claim
84 words
A modifier for composite materials comprising an amino group-containing silicon compound of the general formula: ##STR19## wherein R 1 is a monovalent hydrocarbon group having 1 or 2 carbon atoms, R 2 is a divalent aromatic ring-containing hydrocarbon group having 6 to 10 carbon atoms, R 3 is a divalent hydrocarbon group having 2 to 8 carbon atoms, X is an alkoxy group having 1 or 2 carbon atoms, and n is a number equal to 0, 1 or 2, or a hydrochloride thereof.
Claim 3
Dependent Claim
30 words
The modifier according to claim 1, wherein the compound of formula (I) is in the form of a solution which is suitable for treating the matrix of a composite material.
Claim 4
Dependent Claim
21 words
The modifier according to claim 2, wherein the solution contains 0.2 to 2% by weight of the compound of formula (I).
Claim 5
Dependent Claim
112 words
A composite material comprising a matrix selected from the group consisting of glass fiber forms and mica forms and a resin binder binding said matrix, wherein said matrix has applied thereto a modifier comprising an amino group-containing silicon compound of the general formula: ##STR20## wherein R 1 is a monovalent hydrocarbon group having 1 or 2 carbon atoms, R 2 is a divalent aromatic ring-containing hydrocarbon group having 6 to 10 carbon atoms, R 3 is a divalent hydrocarbon group having 2 to 8 carbon atoms, X is an alkoxy group having 1 or 2 carbon atoms, and n is a number equal to 0, 1 or 2, or a hydrochloride thereof.
Claim 6
Dependent Claim
112 words
A composite material comprising a matrix selected from the group consisting of glass fiber forms and mica forms and a resin binder binding said matrix, wherein said matrix has applied thereto a modifier comprising an amino group-containing silicon compound of the general formula: ##STR20## wherein R 1 is a monovalent hydrocarbon group having 1 or 2 carbon atoms, R 2 is a divalent aromatic ring-containing hydrocarbon group having 6 to 10 carbon atoms, R 3 is a divalent hydrocarbon group having 2 to 8 carbon atoms, X is an alkoxy group having 1 or 2 carbon atoms, and n is a number equal to 0, 1 or 2, or a hydrochloride thereof.
Claim 7
Dependent Claim
16 words
The modifier of claim 1, wherein R 2 is selected from the group consisting of ##STR21##
