Title:
FIBER STRUCTURE AND FIBER-REINFORCED COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2021/033484
Kind Code:
A1
Abstract:
This fiber structure (11) comprises a first fiber base material (12) and a second fiber base material (20). The first fiber base material (12) has a main body portion (11a) in which a plurality of fiber layers (13a, 13b) of reinforcing fibers are laminated, and a branched portion (18) in which the main body portion (11a) branches in two along the lamination direction (Z) of the fiber layers (13a, 13b). The second fiber base material (20) covers the branched portion (18) and is integrated with the first fiber base material (12). The fiber structure (11) comprises space-filling members (30, 40) that fill spaces (S) defined by the branched portion (18) and the second fiber base material (20), the space-filling members (30, 40) being fiber bundles of discontinuous fibers (H).
