Title:
CARBON FIBER SHEET MANUFACTURING METHOD AND CARBON FIBER SHEET PRODUCT
Document Type and Number:
Japanese Patent JP2023112281
Kind Code:
A
Abstract:
To provide a carbon fiber sheet manufacturing method capable of suppressing generation of defects and metal (particularly, iron) foreign substance contamination by preventing burning or deterioration of a heat-resistant sheet, a heat treatment furnace, and a carbon fiber sheet precursor due to oxygen.SOLUTION: A carbon fiber sheet manufacturing method manufactures a carbon fiber sheet by continuously transporting a carbon fiber sheet precursor and a heat-resistant sheet placed on the carbon fiber sheet precursor and passing them through the inside in inert atmosphere of a heat treatment furnace. The heat-resistant sheet is separated away from the carbon fiber sheet precursor at an inlet of the heat treatment furnace and placed on the carbon fiber sheet precursor in a furnace inner space of the heat treatment furnace.SELECTED DRAWING: Figure 1
