Abstract
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.
