If the laminate structure has no eaves, it has extremely high strength and is effective in making products lightweight and high-performance, but when subjected to impact etc., delamination occurs between the laminate layers. Laminate structures are generally made by laminating continuous sheet-like materials (prepreg), so once the delamination between the layers occurs as shown in Figure 4A, it will progress under load as shown in Figure 4B. Once it starts, it cannot be stopped midway through and results in total destruction. This load is far lower than the strength of the laminate, and its excellent properties cannot be fully utilized.
上記の欠点を克服できれば、積層体構造はより

If the above drawbacks can be overcome, the laminate structure can be made lighter and more efficient. For this reason, stitching (stitching in the thickness direction) and three-dimensional fabrics are currently being considered, but these have drawbacks such as the need for special equipment and restrictions on shape, size, etc.
本考案は、通常の積層加工中に適用可能で、且
