PURPOSE:To obtain a laminate excellent in resistance to warp, by impregnating sheet bases comprising a specified nonwoven cloth with a resin, drying the bases and laminate-molding the obtained prepregs. CONSTITUTION:Sheet bases comprising nonwoven cloth (e.g., paper) which shows a warp <=5% when it is heated in a temperature range of the glass transition temperature of the resin with which the bases are impregnated + or -20 deg.C and cooled are impregnated with a resin (e.g., epoxy resin) and dried to obtain prepregs. These prepregs are laminate-molded. |
