PROBLEM TO BE SOLVED: To provide a radiation curable resin composition with excellent reactivity, and a prepreg for molding a composite material and members comprising the resin and a fiber reinforcement usable especially in the aeronautical or space field, and especially, a resin composition having compression characteristics and interlayer shear strength superior to those of conventional ones and advantageous in terms of cost. SOLUTION: The radiation curable resin composition is provided, which comprises 100 pts.mass of a component (A) comprising an epoxy resin and/or an oxetane resin, 1-100 pts.mass of a modifier component (B), such as a thermoplastic resin, a non-amine-based coupling agent component (C), such as an epoxy-based silane coupling agent, and an initiator component (D), such as an iodonium salt type that generates an acid by radiation. The prepreg obtained by impregnating such a radiation curable resin composition into the fiber reinforcement and the composite material are also provided. COPYRIGHT: (C)2011,JPO&INPIT
