MANUFACTURING METHOD OF ONE WAY PREPREG AND APPARATUS THEREOF

PURPOSE: A one-way prepreg manufacturing method and a device are provided to control a width change of prepreg at both ends by a viscosity difference of resin because temperatures of both sides of an impregnation roller is lower than a temperature of the central part of the impregnation roller.

Zusammenfassung:	PURPOSE: A one-way prepreg manufacturing method and a device are provided to control a width change of prepreg at both ends by a viscosity difference of resin because temperatures of both sides of an impregnation roller is lower than a temperature of the central part of the impregnation roller. CONSTITUTION: A one-way prepreg manufacturing method is as follows. A resin of a resin film penetrates through impregnation rollers(50) after the upper and lower surfaces of the fiber is wrapped with resin films(200), thereby being impregnated on the upper and lower surfaces. When the resin film and the fiber penetrates the impregnation roller, both sides of the impregnation roller is controlled to be lower than a temperature of the central part of the impregnation roller.
