Abstract
Official abstract text for this publication.
A fabric laminate used as a reinforcing base material of a fiber-reinforced composite is constituted by laminating fabrics having warp yarns and weft yarns. Each warp yarn has a diameter-changing portion, in which the diameter of the yarn gradually changes in the yarn longitudinal direction in the vicinity of one end in the yarn longitudinal direction of the warp yarn.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fiber-reinforced composite, comprising: a reinforcing base material, which is made of a fabric having a warp yarn and a weft yarn, wherein at least one of the warp yarn and the weft yarn has a diameter-changing portion, in which a diameter of the yarn gradually changes in a yarn longitudinal direction, the yarn that has the diameter-changing portion is made of discontinuous fibers, the reinforcing base material is impregnated with a matrix resin, and the fiber-reinforced composite has or is a thickness-changing portion, in which a thickness of the fiber-reinforced composite gradually changes in correspondence with a gradual change in a diameter of the diameter-changing portion, and a thickness of the fiber-reinforced composite increases in the yarn longitudinal direction from a first edge of the fiber-reinforced composite to a second edge of the fiber-reinforced composite. 2. The fiber-reinforced composite according to claim 1 , wherein the reinforcing base material is constituted by laminating a plurality of fabrics in a thickness direction of each fabric. 3. The fiber-reinforced composite according to claim 1 , wherein the warp yarn has the diameter-changing portion. 4. The fiber-reinforced composite according to claim 1 , wherein the warp yarn and the weft yarn each have the diameter-changing portion. 5. The fiber-reinforced composite according to claim 1 , wherein the weft yarn has the diameter-changing portion.
