ができないという問題があった。However, in the conventional structure, the FRM reinforced by the alumina silica short fibers has a constant strength in all directions, and as a result, wear resistance. Although it has excellent strength and strength against twisting, and has the advantage of being easy to process, it is a fiber against tensile stress hanging in the axial direction of the bolt where the direction in which stress is generated is almost fixed. Does not have sufficient directionality because it does not have directionality, and if the tightening force of the bolt becomes large, the bolt will be damaged, so a large tightening force like an iron bolt will occur. There was a problem that it could not be used where needed.

や、捩じりに対しては脆いという欠点を有している。First, as a characteristic of FRM reinforced by long fibers of alumina silica, it has an advantage that the tensile strength in the axial direction of the fiber is high, but it is in a direction other than the axial direction of the fiber (direction perpendicular to the axial direction of the fiber). ) Is fragile with respect to tension and twist.

という長所を有している。On the other hand, since the FRM reinforced by alumina silica short fibers has no directional property as a characteristic, the tensile strength in a certain direction like long fibers is inferior to that of long fibers, but in all directions. Since it has a constant strength against the force of, it has excellent wear resistance and excellent strength against twisting that occurs in various directions of the bolt,
Since the alumina silica fibers are granular or short fibers, it is sufficient to process a mixture of aluminum and alumina silica short fibers at the time of processing, which has an advantage that processing such as cutting is easy.
