CARBON FIBER PRECURSOR ACRYLIC FIBER BUNDLE, CARBON FIBER BUNDLE, AND MANUFACTURING METHOD OF CARBON FIBER BUNDLE

摘要

PROBLEM TO BE SOLVED: To provide a carbon fiber precursor acrylic fiber bundle having high carbon yield.;SOLUTION: The carbon fiber precursor acrylic fiber bundle comprises an acrylonitrile-based polymer containing 0.001-0.14 mass% (inclusive) of phosphorus atom. By carbonization of a flame-resistant fiber bundle obtained from the carbon fiber precursor acrylic fiber bundle in an inert atmosphere, carbon fiber bundle can be obtained with high carbon yield.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
