摘要： The present invention provides a resin composition for a fiber-reinforced plastic, the resin composition including a cyanate ester (A), an epoxy resin (B), and an aromatic amine-based curing agent that is liquid at 25°C (C), wherein the average number of cyanate groups in the cyanate ester (A) is 2.1 or greater, and/or the average number of epoxy groups in the epoxy resin (B) is 2.1 or greater. A fiber-reinforced plastic that is produced using this composition and a reinforcing fiber has favorable heat resistance and excellent tensile and bending properties, and therefore can be applied to a wide variety of fields including transport vehicles such as ships, automobiles, and aircrafts, sporting goods, building materials such as sinks and window frames, as well as industrial machinery and materials such as high-pressure gas tanks and blades for wind power generation.

摘要： It is an object of the present invention to provide a structural material-bonding adhesive capable of bonding materials other than iron, and maintaining the bonding ability in an environment at a high temperature and a low temperature, while maintaining performance similar to that of a structural material adhesive used as an adhesive for bonding iron materials. The present invention is directed to a curable resin composition containing an epoxy resin (A), blocked urethane (C), and an amine-based latent curing agent (D), wherein the blocked urethane (C) is obtained by reacting a urethane polymer having a terminal isocyanate group with a blocking agent (C-4), the urethane polymer being obtained by reacting a polyisocyanate (C-1), a diol (C-2), and a branching agent (C-3) containing at least three groups that react with an isocyanate group.

摘要： Provided is a resin composition that is capable of producing a cured product having excellent environmental suitability, high strength, and excellent flame retardancy, and that is suitably usable as a matrix resin for fiber-reinforced plastics. A resin composition contains (A) an epoxy resin, (B) a cyanate resin, (C) an aromatic amine curing agent that is liquid at 25°C, and (D) a phosphorus-containing compound represented by formula (1). Preferably, in formula (1), R 1 and R 2 each independently represent an alkyl group or an aryl group, and X and Y are an oxygen atom.
