て行なわれる。(Means for Solving the Problems) In the first invention, resin-impregnated fibers are wound around the circumferential surface of a mandrel, and then the resin contained in the fibers is cured.
The method for manufacturing a rod made of fiber-reinforced resin includes the steps of previously forming a thread on the end of the mandrel, and removing the mandrel after the resin has hardened. Further, in the second invention, the step of winding the resin-impregnated fiber on the mandrel so as to form a layer of a predetermined thickness, and the step of wrapping the resin-impregnated fiber on the mandrel so as to form a layer with a predetermined thickness, and on the layer located at the end of the mandrel,
A step of winding the resin-impregnated fiber to form a screw thread is performed. [Function] According to the present invention, an FRP rod having a threaded end is formed. [Examples] Examples of the present invention will be described below with reference to the drawings. FIG. 1 shows a mandrel 20 used in an embodiment of the present invention.
This mandrel 20 has screw threads 21 and 22 formed on the circumferential surfaces of one end and the other end, respectively.
The mandrel 20 is made of a crushable material such as gypsum or stone. In this embodiment, the FW method is performed using this mandrel 20. That is, the mandrel 20 is rotated and the fiber 23 (for example, carbon fiber) impregnated with a thermosetting resin in advance is wound around the mandrel 20. At this time, mandrel 2

く生じない．FIG. 2 shows a state in which a layer of uniform thickness of fibers 23 is formed on the circumferential surface of the mandrel 20. After this layer of fibers 23 is formed, the layer is heated in a rotary heating furnace (not shown), thereby causing the fibers 23 to be heated.
The thermosetting resin impregnated in Step 3 is cured. Note that the heating temperature of the heating furnace, etc. is approximately 150° C. when carbon fiber is used as the fiber 23 and epoxy resin is used as the resin. After the resin hardens, the mandrel 20 is crushed and removed, resulting in a cylindrical FRP rod 24 as shown in FIG. 3, with the fibers 23 as a reinforcement and the resin as a matrix (base material). is molded. Threads 25 and 26 based on the threads 21 and 22 shown in FIG. 1 are formed on the inner peripheral surface of both ends of the rod 24. Therefore, by screwing the male thread 28 of the fitting 27 and the male thread 30 of the fitting 29 into the threads 25 and 26, respectively, a rod with a fitting is completed. Figure 4 shows another example of a mandrel. Since the mandrel 20' shown in the figure has a three-part structure in which the threads 21 and 22 are divided, it can be removed from the molded product without being crushed, and therefore can be reused. Although the rod 24 in the above repair example has a female thread formed by threads 25 and 26, it is also possible to mold a rod with a male thread using the FW method. In this case, a cylindrical mandrel 31 as shown in FIG. 5 is used, and a fiber cod 32 pre-impregnated with a thermosetting resin is wound around the circumferential surface of this mandrel 31. Then, as shown in FIG. 6, when a layer of uniform thickness of aa32 is formed, screw threads are formed on the circumferential surfaces of both ends of this layer. That is, by properly orienting the fibers 32 with the delivery eye 33, the fibers 32 are wound in a threaded manner as shown in FIG. 7, thereby forming threads 34 and 35 as shown in FIG. ．． After forming the threads 34 and 35,
The resin impregnated into the fibers 32 is heated and cured, and as a result, an FRP with male screws at both ends as shown in FIG.
A rod 36 made of aluminum is molded. Therefore, the female thread 38 of the fitting 37 and the fitting 39 are
An FRP rod with a joint is completed by screwing the female screws 40 into the screw threads 34 and 35, respectively. Note that in this embodiment, the mandrel 31 does not need to be removed. [Effects of the Invention] According to the present invention, an FRP rod having a threaded end is formed. Therefore, by using a joint fitting with a threaded part, this joint can be installed easily and firmly. Furthermore, the conventional FRP shown in Fig. 10
If a screw thread is formed on the inner circumferential surface of the end of the rod 7 made of steel by cutting or other means, the strength of the rod will be significantly reduced because the reinforcing fibers will be broken. According to the present invention, such inconvenience does not occur at all.
