摘要： 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.

摘要： A method of producing a partially separated fiber bundle includes a partial separation processing step for alternately forming separation-processed sections, each divided into a plurality of bundles, and not-separation-processed sections along the lengthwise direction of a fiber bundle, wherein a separation means provided with a plurality of projected parts is penetrated into the fiber bundle to create separation-processed parts, the separation means is removed from the fiber bundle, and the separation means is penetrated into the fiber bundle again, characterized in that a sizing agent is applied at an arbitrary timing during the production process of the partially separated fiber bundle. A partially separated fiber bundle is obtained by the production method, a fiber-reinforced resin molding material uses the partially separated fiber bundle, and a production method makes the fiber-reinforced resin molding material.
