CARBON FIBER STRAND AND METHOD FOR PRODUCING CARBON FIBER-REINFORCED COMPOSITE MATERIAL MOLDED ARTICLE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To make a recycle carbon fiber sliver into a usable strand with a common kneader and to provide a method for producing a molded article using the strand.;SOLUTION: A carbon fiber-containing sliver in which a discontinuous carbon fiber and a synthetic fiber are aligned in one direction is twisted into a twist yarn. Alternatively, a film or a yarn like article comprising a synthetic resin is wound. Thereby, the carbon fiber strand is formed in string-like shape and contains the discontinuous carbon fiber in range of 10-60 vol%.;SELECTED DRAWING: Figure 5;COPYRIGHT: (C)2018,JPO&INPIT
