Definitions
- a three-dimensional fiber reinforced composite material is used as a lightweight and high-strength material.
- the three-dimensional fiber reinforced composite material has a laminate formed by binding a plurality of fiber bundle layers with binding yarns in a matrix resin.
- the three-dimensional fiber reinforced composite material is preferable as a structural component because it is superior in mechanical properties (mechanical properties) compared to a material containing only a matrix resin.
- the three-dimensional fiber reinforced composite material has improved strength in the stacking direction due to the binding yarn as compared with the two-dimensional fiber reinforced composite material.
- the three-dimensional fiber reinforced composite material 80 of Patent Document 1 has a flat three-dimensional woven fabric 86, and the three-dimensional woven fabric 86 includes a plurality of warp yarns 81 and a plurality of weft yarns 82.
- the three-dimensional woven fabric 86 is impregnated with resin, and the resin is cured to form a three-dimensional fiber reinforced composite material 80.
- the out-of-plane direction yarn 84 is inserted into the three-dimensional woven fabric 86 and the sewing proceeds, the out-of-plane direction yarn 84 is pulled in a direction along the surface of the three-dimensional woven fabric 86. It is done. For this reason, a large gap is formed by pulling in a portion where the out-of-plane direction yarn 84 extends in the opposite direction (a portion that is bifurcated).
- the resin remains in the gap and a resin reservoir 87 is formed.
- This resin reservoir 87 is a portion where the mechanical strength of the three-dimensional fiber reinforced composite material 80 is low because it does not contain fibers. Therefore, it is desired to make the resin reservoir 87 small.

- the retaining layer 15 is a woven fabric formed by plain weaving warps 15a and wefts 15b. For this reason, the warp yarn 15a and the weft yarn 15b suppress an increase in the interval defined by the warp yarn 15a and the weft yarn 15b. Therefore, even if the binding yarn 21 is pulled, the holding layer 15 itself does not spread and the bifurcated portion 21e. Can be prevented from spreading.

- the first retaining thread 22 and the second retaining thread 23 were made of carbon fiber. For this reason, even if the first retaining thread 22 and the second retaining thread 23 are pulled by the binding thread 21, the first retaining thread 22 and the second retaining thread 23 are not easily cut, and the laminate 20 is bound. Can be maintained.
