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 filaments composed of 30,000-120,000 carbon fibers, and a sizing agent content 1-10% by weight that bundles the single filaments; 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 a repose angle of 10-30°.
