Title:
PRODUCTION METHOD OF CARBON FIBER
Document Type and Number:
Japanese Patent JP2021080607
Kind Code:
A
Abstract:
To provide an efficient production method of carbon fiber excellent in fiber openability, from which a prepreg or fabric excellent in appearance quality can be obtained, with reduced problems in a step of firing a fiber bundle of carbon fiber precursor to make carbon fiber.SOLUTION: A production method of carbon fiber includes production steps of a fiber bundle of carbon fiber precursor including recording data of continuous evaluation on a running fiber bundle of carbon fiber precursor, determining a problematic part based on the recorded data, and firing the fiber bundle of carbon fiber precursor with the problematic part removed.SELECTED DRAWING: Figure 1
