FIBER STRUCTURE FOR FIBER REINFORCED COMPOSITE MATERIAL, METHOD FOR MANUFACTURING FIBER STRUCTURE FOR FIBER REINFORCED COMPOSITE MATERIAL, AND FIBER REINFORCED COMPOSITE MATERIAL

摘要

A fiber structure for a fiber-reinforced compositematerial includes a section in which a width variescontinuously along a central axis in a plan view. In asection in which the width increases continuously along thecentral axis, discontinuous fibers are aligned radiallyalong the central axis, and both a thickness of the fiberstructure and a density of the discontinuous fibers areuniform.
