PRODUCTION OF PREPREG AND LAMINATE

摘要

PROBLEM TO BE SOLVED: To obtain a good laminate not causing air pollution, capable of saving resources and having a stable quality at a low cost. SOLUTION: This method for producing a prepreg 3 comprises allowing a powdery resin 2 to exist on a sheet-like substrate 1 comprising a fibrous material and subsequently heating the resin-existing sheet-like substrate. Therein, the method has a process for allowing the powdery resin to exist on one surface side of the sheet-like substrate, a process for heating the powdery resin-existing surface at a higher temperature than the temperature of the opposite surface, and a process for heating the resin-existing sheet-like substrate.
