Abstract
An object of the present invention is to provide a composite material including an epoxide resin, having an improved strength. The object can be solved by a curable epoxide composition comprising an epoxide compound; a carbon fiber; a curing agent; and phosphite ester or phosphate ester. According to the present invention, a strength of the curable epoxide composition comprising a carbon fiber can be improved.
Claims
exact text as granted — not AI-modified1 . An adhesive comprising a curable epoxide composition, wherein the curable epoxide composition comprises an epoxide compound; a carbon fiber; a curing agent; and phosphite ester or phosphate ester.
2 . The adhesive according to claim 1 , wherein an average fiber length of the carbon fiber is 20 μm to 1 mm.
3 . The adhesive according to claim 1 , wherein an amount of phosphite ester or phosphate ester is 2 to 40% by weight.
4 . The adhesive according to claim 1 , the curable epoxide composition further comprises a humed silica and/or a rheological agent.
