PURPOSE: A composition for preparing fiber reinforced plastic for inner strength member of overhead transmission line is provided to maintain stable thermal characteristics and high tensile property at high temperature through use of fiber reinforced plastic, and to prevent the sagging phenomenon of wires. CONSTITUTION: A composition for preparing fiber reinforced plastic for inner strength member of overhead transmission line includes a polyfunctional epoxy resin and an aromatic amine-based hardener. The polyfunctional epoxy resin is tri-functional or multi-functional epoxy resin. The aromatic amine-based hardener is included in the amount of 10-50 weight% based on 100 weight% of the polyfunctional epoxy resin. The aromatic amine-based hardener is meta phenylene diamine, 4,4-dimethylaniline, diamino diphenyl sulfone or mixture thereof.
