摘要： A reinforcing fiber bundle is a continuous reinforcing fiber bundle having a length of at least 1 m and is characterized by the number of monofilaments per unit width being at most 1,600/mm and the average number of fibers in the bundle being at most 1,000 in a region (I), and the drape level found in a region (II) being 120-240 mm. The continuous reinforcing fiber bundle has a length of at least 1 m and is characterized by the adhesion amount of a sizing agent (I) in the region (I) being 0.5-10% by weight and the drape level found in the region (II) being 120-240 mm. The continuous reinforcing fiber bundle has superior mechanical properties, formability into complex shapes, and continuous producibility.

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.
