PROBLEM TO BE SOLVED: To provide a fiber-reinforced composite material and its manufacturing method, in which a curing time is short, and a manufacturing cost is low, and which can be used also for large-size fiber-reinforced composite materials whose forming takes a long time, are easy to keep the impregnated state, do not deteriorate the quality of moldings by the occurrence of voids, and do not need a heating process in curing. SOLUTION: A cationic polymerizable resin composition which comprises the effective amount of sulfonium salt (I) that is Lewis acid and cationic polymeric substances, and has a thermosetting property and energy ray curability at the same time is used as a matrix resin. Prepregs obtained by impregnating the matrix resin in glass fibers are laminated to give a prepreg lamination having a thickness of two to three mm. COPYRIGHT: (C)2005,JPO&NCIPI |
