CARBON-FIBER CHOPPED STRAND AND MANUFACTURING METHOD OF THE SAME

摘要

Disclosed is a carbon-fiber chopped strand, and a manufacturing method of the same. The carbon-fiber chopped strand is composed of single threads composed of 30,000 - 120,000 carbon fibers, and a sizing agent content 1 - 10% by weight that bundles the single threads; the ratio of maximum diameter (Dmax) in the cross section and minimum diameter (Dmin) is 1.0 - 1.8, a length along a fiber direction is 3 - 10 mm, and an angle of repose of 10 - 30°.
