Abstract

See full text

A partially separated fiber bundle includes a separated fiber section and an unseparated fiber section, being configured to give a ratio Amax/Amin of 1.1 or larger and 3 or smaller, when the number of fiber bundles contained in the width direction of the partially separated fiber bundle (fiber separating number: Nn) measured at a freely selected point Pn (where, n represents an integer of 1 to 100, and freely selected points Pn and Pn+1, excluding n=100, being 50 cm or more away from each other), is divided by a full width of Wn of the partially separated fiber bundle, to calculate the fiber separating number per unit width An, and assuming its maximum value as Amax and its minimum value as Amin.
