摘要： A partially separated fiber bundle includes separation-processed sections, each divided into a plurality of bundles of at least three bundles, and not-separation-processed sections, that are alternately formed along the lengthwise direction of a fiber bundle that comprises a plurality of single fibers. The partially separated fiber bundle is characterized in that, at any width-direction cross-section taken along the lengthwise direction thereof, a rate of single fibers contained in a region at which adjacent divided fiber bundles are joined by a not-separation-processed part is 67% or less relative to the total single fibers in the width-direction cross-section.

摘要： A device for manufacturing a chopped fiber bundle includes a cutter roll provided with one or more disk blades on a circumference of a roll core having a center axis coinciding with a rotation axis of the roll core and a nip roll provided in parallel with the rotation axis of the roll core, to feed a reinforcing fiber yarn to be continuously cut between the nip roll and the cutter roll, further including a rotary drive mechanism that rotates the cutter roll and at least one of: a reciprocating drive mechanism that reciprocates the cutter roll along the rotation axis of the roll core; and a traverse guide that traverses the reinforcing fiber yarn along the rotation axis of the roll core.

摘要： A reinforcing fiber mat manufacturing apparatus according to the present invention is a reinforcing fiber mat manufacturing apparatus that includes a hitting mechanism (40) that comes into contact with a reinforcing fiber bundle to split the reinforcing fiber bundle into a plurality of pieces, and, disperses the plurality of pieces. The hitting mechanism (40) includes a rotation shaft (41), a pair of rotation plates (42) attached to portions of the rotation shaft (41) apart from each other, and a plurality of hitting pieces (43) arranged to extend in parallel to the rotation shaft (41) between the pair of rotation plates (42). The reinforcing fiber mat manufacturing apparatus according to the present invention is a simple apparatus that reliably hits a reinforcing fiber bundle to split the fiber bundle into thin bundles, and disperses the thin bundles to a wide range without causing air turbulence to manufacture a reinforcing fiber mat having a uniform fiber basis weight.

摘要： A method produces a reinforcing fiber sheet in which a plurality of bundles of reinforcing fibers lined up into one direction to form a plane are adhered to one another through a binder in an amount far smaller than that of the bundles. This method includes step (a) of placing a plurality of reinforcing fibers each having any length at any position on a flat plate, and fixing the reinforcing fibers onto the flat plate, step (b) of placing a binder onto the reinforcing fibers to be adhered onto the fibers, and step (c) of separating the reinforcing fibers from the flat plate.
