Abstract
A fibrous structure for reinforcing a composite material which is a bottomed hollow pillar-shaped body having fins extending outwardly from a peripheral side wall of the body. The composite material-reinforcing fibrous structure consists of a plurality of longitudinally adjoining yarn section, each section being a plurality of layers, or tiers, of a first continuous yarn. A second continuous yarn is disposed substantially perpendicularly to the layers of first continuous yarn, and a third continuous yarn passes into loops formed in the second continuous yarn adjacent an outside layer of the first continuous yarn. The second continuous yarn functions as a common longitudinal component yarn in coextensive portions of the adjoining yarn sections and as an independent longitudinal component yarn in portions of the yarn sections which do not adjoin other yarn sections.
