Fiber bundle drawing apparatus, method of drawing fiber bundle, and method of manufacturing fiber composite material

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.
