PURPOSE: To obtain a pre preg excellent in handling properties and free from deterioration of physical properties after the molding caused by impregnating properties thereof. CONSTITUTION: This pre-preg comprises impregnating (C) a reinforcing substrate consisting of fibers with (A) an epoxy resin composition having $50 poise viscosity at 50 deg.C, and laminating resin films of (B) an epoxy resin composition having >=3000 poise viscosity at 50 deg.C to the both sides of the impregnated reinforcing substrate. |
