Carbon fiber sheet and method for manufacturing carbon fiber sheet

Abstract:

A method for manufacturing a carbon fiber sheet, the method including a carbon fiber forming step of heating a resin sheet to a carbonization temperature at a heating rate of 15,000.degree. C./sec or higher, thereby forming a carbon fiber from the resin sheet. In the carbon fiber forming step, the resin sheet is preferably irradiated with an energy ray having an output density of 130 W/mm.sup.2 or higher and an amount of irradiation energy of 0.05 J/mm.sup.2 or more.
