| description | The present invention relates to an epoxy resin composition including at least an appropriate type of epoxy resin, acid anhydride, salt of either diazabicycloundecene or diazabicyclononene and an organic compound, and core shell polymer particles, having a viscosity of 3,000 mPa·s or less at 25°C, and showing a viscosity of 4,500 mPa·s or less 3 hours after the start of measurement when subjected to continued measurement for 3 hours at a temperature of 25°C, by means of which it provides an epoxy resin composition with both a low viscosity and long pot life that serves effectively to produce fiber reinforced composite material with a high heat resistance and high toughness. |
