Abstract
A fiber structure including a multi-layered fabric includes a first fabric layer and a second fabric layer. The first fabric layer and the second fabric layer are stacked one over another in the thickness direction of the multi-layered fabric. A warp yarn in the first fabric layer is thicker than a warp yarn in the second fabric layer, and/or a weft yarn in the first fabric layer is thicker than a weft yarn in the second fabric layer, and a pitch in the first fabric layer is smaller than a pitch in the second fabric layer, where each of the pitches refers to a distance between any two main axes of yarns adjacent to each other in each of the warp layer and the weft layer.
Claims5
A fiber structure used as a reinforcement base material of a fiber-reinforced composite, the fiber structure comprising:
- a multi-layered fabric, wherein
- the fiber structure includes:
- a first fabric layer including a warp layer and a weft layer;
- and
- a second fabric layer including a warp layer and a weft layer, the first fabric layer and the second fabric layer being stacked one over another in a thickness direction of the multi-layered fabric,
- a warp yarn in the first fabric layer is thicker than a warp yarn in the second fabric layer, and/or
- a weft yarn in the first fabric layer is thicker than a weft yarn in the second fabric layer, and
- a pitch in the first fabric layer is smaller than a pitch in the second fabric layer, where each of the pitches refers to a distance between any two main axes of yarns adjacent to each other in each of the warp layer and the weft layer.
