Abstract: There is provided a fiber bundle drawing apparatus that can draw a fiber bundle traverse-wound around a bobbin and having a laterally-elongated cross-sectional shape while maintaining the cross-sectional shape, and cause the fiber bundle to travel along a fixed course. The fiber bundle drawing apparatus includes: a bobbin holder configured to hold the bobbin in a rotatable state; a turning mechanism configured to receive the fiber bundle drawn from the bobbin, and to turn and deliver the fiber bundle, thereby reducing change in course of the fiber bundle in a direction parallel to a center axis of the bobbin; and a twist prevention mechanism provided between the bobbin holder and the turning mechanism in a path of the fiber bundle in the apparatus, and including a support portion and a rotation suppression portion, the support portion coming into contact with the fiber bundle, the rotation suppression portion being disposed to face the support portion with a gap through which the fiber bundle passes, the gap having a distance greater than or equal to a thickness of the fiber bundle and less than or equal to a width of the fiber bundle.

Abstract: A fiber placement device that includes a placement surface on which a reinforcing fiber tow is placed and stacked; a tow arranging mechanism which presses and places the reinforcing fiber tow against and on the placement surface; and a heating mechanism which is configured to heat the placement surface. In one placement cycle, the tow arranging mechanism presses a group of the reinforcing fiber tows against the placement surface heated in advance by the heating mechanism, moves by a predetermined length in a first axial direction to glue and fix the group of the reinforcing fiber tows onto the placement surface, and move the placement surface in a second axial direction which substantially intersects the first axial direction.

Abstract: 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.

Abstract: A carbon fiber preform has a plurality of carbon fiber sheets that are stacked and are bonded to each other by means of an adhesive resin having thermal plasticity. This carbon fiber preform comprises a partial-conducting layer arranged at least either between at least one pair of adjacent layers of the plurality of carbon fiber sheets or on a surface area of the plurality of carbon fiber sheets and configured to have a resistance area which has higher electric resistance than electric resistance of the carbon fiber sheet in a stacking direction and a conductive area which is capable of having electrical continuity in the stacking direction, wherein the resistance area and the conductive area are arranged in a surface direction orthogonal to the stacking direction. The plurality of carbon fibers sheets are bonded to each other by means of the adhesive resin in the surface direction in the conductive area and in an area corresponding to periphery of the conductive area. In areas other than the conductive area and the area corresponding to the periphery of the conductive area, the plurality of carbon fiber sheets are not bonded to each other by means of the adhesive resin.
