Document Type and Number:
WIPO Patent Application WO/2020/158496
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a fiber package made by winding a partially split carbon fiber bundle onto a bobbin, such that the fiber package has no problems in unwinding. Provided is a fiber package that is a square end type fiber package made by traverse winding a fiber bundle (12) onto a bobbin and is characterized in that the fiber bundle (12) is partially split into sub bundles (11) and the width W of the fiber bundle (12) is smaller than the total of the widths WS of the sub bundles (11). Also provided is a fiber package that is a square end type fiber package made by traverse winding a fiber bundle (12) onto a bobbin and is characterized in that the fiber bundle (12) is partially split into sub bundles (11) and is wound onto the bobbin so that overlap occurs between sub bundles (11).
