Abstract
The invention is directed to chopped strands of carbon fibers in which 0.3-5% by weight of carbonaceous spherules are present between filaments of carbon fibers. The chopped strands of carbon fibers can be used in spinning. During production, the chopped strands include water, or an organic medium, in which 1-15% by weight of carbonaceous spherules are dispersed. The chopped strands of carbon fibers show no fusion of filaments together, are excellent in separationability and easily disperse in a matrix while maintaining excellent bundling properties.
Claims4
