Title:
FIBER STRUCTURE AND FIBER-REINFORCED COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/204058
Kind Code:
A1
Abstract:
This fiber structure comprises a plurality of fiber layers and a plurality of inter-layer joining threads. The plurality of fiber layers comprise a plurality of first thread layers and one or more second thread layers. Each of the first thread layers includes a plurality of first threads, the main thread axis of which extends in a first direction. Each of the second thread layers has an end second fiber which is positioned at an end part of a center region. The plurality of inter-layer joining threads positioned at an end part region include two inter-layer joining threads that, in a cross-section of the fiber structure orthogonal to the first direction, run along differing paths from each other and are entangled with respect to first threads. The pitch interval in the first direction of inter-layer joining threads in the end part region is less than the pitch interval in the first direction of inter-layer joining threads in the center region.
