ABSTRACT:
A carbon fiber chopped strands suitable for use in production of a composite with a matrix material, which have a circular or elliptical cross-section, wherein carbon fiber filaments are bundled by a sizing agent in an amount of from 1 to 10% by weight based on the chopped strand, and which have denseness of from 0.4 to 0.9 according to the formula below: ##EQU1## where D denotes the average diameter of the chopped strands, d denotes the average diameter of filaments constituting the chopped strand and N denotes the number of the filaments, and a method for production thereof by impregnating a carbon fiber strand with a sizing agent in an amount of from 1 to 10% by weight based on the total weight of the chopped strand to form a sized strand, and then cutting the sized strand, thereby giving the denseness of from 0.4 to 0.9 according to the formula (1).
