Fiber reinforced resin member and method of manufacturing the same, and apparatus manufacturing fiber fabric

An apparatus manufacturing a fiber fabric, the apparatus manufacturing an elongate fiber fabric by braiding a plurality of longitudinal yarns extending in a longitudinal direction of the fiber fabric and a plurality of diagonal yarns inclined at a predetermined angle to the longitudinal direction, the apparatus comprising:

• a first braider and a second braider installed at a distance from each other;
• a first bobbin installed in the first braider to supply the diagonal yarns, and a second bobbin installed in the second braider to supply the longitudinal yarns;
• moving means, which includes a positioning member and an elongated moving rail, wherein the mandrel having at least a bent portion fixed at upper ends of the positioning member extending vertically from opposite ends of the moving rail so that the moving rail can be moved by a servo motor or a cylinder mechanism to cause the mandrel to pass through the substantial center of the central opening of each annular portion of the first and second braiders in a direction from the second braider toward the first braider and so as to prevent the mandrel from interfering with both the first and second braiders;
• and
• control means that rotates both the first and second braiders at the bent portion of the mandrel.
