Title:
FIBER STRUCTURE AND FIBER-REINFORCED COMPOSITE MATERIAL
Document Type and Number:
Japanese Patent JP2023160586
Kind Code:
A
Abstract:
To provide a fiber structure capable of suppressing fraying from an end of the fiber structure while suppressing an increase in man-hours for manufacturing the fiber structure.SOLUTION: In a fiber structure 11 composed of a plurality of fiber layers 20, the plurality of fiber layers 20 comprises a plurality of first yarn layers 21 in which a plurality of first yarns 31 having a yarn main axis extending in a first direction X are arranged in a second direction Y, and a plurality of second yarn layer 22 in which a plurality of second yarns 32 having a yarn main axis extending in the second direction Y are arranged in the first direction X without being entangled with the first yarns 31. The second yarn layer 22 has a terminal second yarn 32a which is a second yarn 32 located at an end portion Rc of a central region Ra. A plurality of interlayer binding yarns 35 located in a terminal region Rb include two interlayer binding yarns 35 which are entangled with the first yarns 31 via different paths in a cross section of the fiber structure orthogonal to the first direction X. The pitch interval in the first direction X between the interlayer binding yarns 35 in the terminal region Rb is smaller than that in the first direction X between the interlayer binding yarns 35 in the central region Ra.SELECTED DRAWING: Figure 2
