PROBLEM TO BE SOLVED: To provide an epoxy resin composition compounded with an aminotriazine-modified novolak resin, capable of facilitating the control of its pot life after compounded with the above novolak resin and the gelling time or the like of a prepreg worked using the composition without deteriorating the physical properties of the cured product thereof, and to provide a method for controlling the curing rate of the above composition. SOLUTION: This epoxy resin composition essentially comprises an aminotriazine-modified novolak resin and an epoxy resin and optionally contains other novolak resin(s); wherein it is characteristic that the molar ratio: (the total number of moles of the hydroxy groups in the novolak resin(s))/(the number of moles of the epoxy groups in the epoxy resin) is 0.30-0.80. |
