<P>PROBLEM TO BE SOLVED: To provide a large-sized molding resin composition having high compression performance. <P>SOLUTION: The large-sized molding resin composition contains an alicyclic epoxy resin (a), a multi-functional epoxy resin (b), an acid anhydride curing agent (c), a phenol curing agent (d) having 3 or less-function and a curing catalyst (e), and is characterized in that the multi-functional epoxy resin (b) is formulated at a ratio of 5-50 pts.mass in the total epoxy resin. The resin composition can be manufactured, which is also provided with high compression rigidity and high compression elongation, has the high compression performance, has low viscosity at a working temperature and has resin viscosity suitable for RTM molding by addition of the multi-functional epoxy resin (b), the acid anhydride curing agent (c) and the phenol curing agent (d) having 3 or less-function in addition to high rigidity possessed by the alicyclic epoxy resin (a). <P>COPYRIGHT: (C)2011,JPO&INPIT |
