Abstract
A fibrous structure includes a main plate and a sub-plate. The main plate, which is formed by a multi-layer textile, includes a plurality of stacked fiber layers. Each fiber layer includes main plate warps and main plate wefts. The sub-plate, which is formed by a multi-layer textile, includes a plurality of stacked fiber layers. Each fiber layer includes sub-plate warps and sub-plate wefts. The main plate and the sub-plate are integrally woven with each other in a state intersecting each other. The main plate wefts and the sub-plate wefts have a smaller volume density at an intersecting portion where the main plate and the sub-plate intersect than a portion separate from the intersecting portion.
