剛性に優れる等の効果を有する。(Effects of the Invention) As described above, according to the structural material of the present invention, the aromatic polyamide Rm, which has extremely excellent tensile strength but lacks rigidity, is incorporated into the fiber body in the form of a braid. Although it has excellent tensile strength and excellent rigidity along the direction, it is difficult to knit it into a braid-like shape due to its rigidity.If a core body is provided, which is made by aligning carbon fibers in parallel, it will trap these aromatics. Since the polyamide PRm and carbon fibers are bonded to each other with a binder, the brittle carbon fRm is protected by the aromatic polyamide fibers, and these fibers are integrated, resulting in extremely high tensile strength of the fiber body. ) The strength is combined with the extremely high mechanical rigidity of the core, resulting in excellent tensile strength and rigidity.
