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° 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/mm2 or higher and an amount of irradiation energy of 0.05 J/mm2 or more.
Claims15
A method for manufacturing a carbon fiber sheet, the method comprising:
- a carbon fiber forming step of heating a resin sheet to a carbonization temperature at a heating rate of 15,000° C./sec or higher to form the resin sheet into a carbon fiber form,
- wherein, in the carbon fiber forming step, the resin sheet is irradiated with an energy ray having an output density of 130 W/mm2 or higher and an amount of irradiation energy of 0.05 J/mm2 or more to form the resin sheet into a carbon fiber form.
A carbon fiber sheet in which at least a part of a resin sheet is formed into a carbon fiber form by being heated to a carbonization temperature at a heating rate of 15,000° C./sec or higher, by irradiation with an energy ray having an output density of 130 W/mm2 or higher and an amount of irradiation energy of 0.05 J/mm2 or more.
