METHOD FOR PRODUCING LONG CARBON FIBER SHEET, LONG CARBON FIBER SHEET PRECURSOR, AND LONG CARBON FIBER SHEET

摘要

PROBLEM TO BE SOLVED: To provide a nonwoven fabric-like or paper-like long carbon fiber sheet precursor or carbon fiber sheet, and to provide a method for producing the carbon fiber sheet precursor and carbon fiber sheet, by which the carbon fiber sheet precursor or carbon fiber sheet can efficiently be produced at a low cost in excellent productivity.;SOLUTION: The method for producing the long carbon fiber sheet comprises sequentially temporarily fixing sheet-like adhesive materials (13) comprising carbon fiber precursors impregnated with a phenolic resin on the final end portion of the first carbon fiber sheet precursor (11) or the starting end portion of the second carbon fiber sheet precursor (12) to be bound, superposing the starting end portion of the second carbon fiber sheet precursor (12) on the final end portion of the first carbon fiber sheet precursor (11), adhering the superposed portion (20) with a heat press device (35) to bind the precursors to each other, and then continuously carbonizing the bound long carbon fiber sheet precursor (16). Preferably, the sheet-like adhesive materials (13) on the binding portion are discontinuously temporarily fixed in the longitudinal direction of the sheet.;COPYRIGHT: (C)2011,JPO&INPIT
