Title:
三次元繊維構造体及び複合材並びに三次元繊維構造体の製造方法
Document Type and Number:
Japanese Patent JP4677950
Kind Code:
B2
Abstract:
A fiber lamination (12) includes a plurality of fiber layers (12a, 12b) laminated on one another. The fiber layers (12a, 12b) are at least biaxially oriented. The fiber lamination (12) is a three-dimensional plate. The fiber lamination (12) includes a bent portion (14a, 14b), a first flat portion (15b), and a second flat portion (15a, 15c). The angle at which a connection yarn (13) crosses the fiber layers (12a, 12b) at the first flat portion (15b) differs from the angle at which the connection yarn (13) crosses the fiber layers (12a, 12b) at the second flat portion (15a, 15c). Therefore, a three-dimensional fiber structure is manufactured by bending a laminated body while suppressing generation of wrinkles and distortion at the bent portion (Fig. 1A).
