<P>PROBLEM TO BE SOLVED: To provide an epoxy resin composition for fiber-reinforced composite materials, little affecting human bodies, and excellent in physical properties. <P>SOLUTION: The epoxy resin composition for the fiber-reinforced composite materials is characterized by comprising an alicyclic epoxy resin (A), a bi-or more-functional liquid epoxy resin (B), a bi- or more-functional reactive diluent (C), an acid-anhydride curing agent (D), and a curing accelerator (E), wherein the content of the alicyclic epoxy resin (A) is 5-20 mass% per the total mass of the alicyclic epoxy resin (A), the bi-or more-functional liquid epoxy resin (B), and the bi- or more-functional reactive diluent (C); the content of the bi- or more-functional reactive diluent (C) is 0-20 mass%; the content of the acid-anhydride curing agent (D) is such a value that the theoretical compounding ratio of the acid anhydride contained in the acid-anhydride curing agent (D) is 0.9-1.3 equivalents based on epoxy groups contained in the alicyclic epoxy resin (A), the bi-or more-functional liquid epoxy resin (B), and the bi- or more-functional reactive diluent (C). <P>COPYRIGHT: (C)2013,JPO&INPIT |
