Abstract
A fiber lamination includes a plurality of fiber layers laminated on one another. The fiber layers are at least biaxially oriented. The fiber lamination is a three-dimensional plate. The fiber lamination includes a bent portion, a first flat portion, and a second flat portion. The angle at which a connection yarn crosses the fiber layers at the first flat portion differs from the angle at which the connection yarn crosses the fiber layers at the second flat portion. Therefore, a three-dimensional fiber structure is manufactured by bending a laminated body while suppressing generation of wrinkles and distortion at the bent portion.
