料を充填して補修していた（特開昭５５−６３６２０お
よび特開昭６０−８９３３８号公報参照）。Generally, when cracks or damaged parts exist on the surface or inside of a fiber-reinforced plastic (FRP) structure, the strength of the material decreases, so it is necessary to repair the parts. For this purpose, in the past, a grindstone was attached to a hand grinder, the damaged part was cut into a trapezoidal shape, and the damaged part was filled with a material of the same quality as the structure to repair it (Japanese Patent Application Laid-Open No. 55-63620 and 60-89338).
しかしながら、上述した従来技術によると、被切削材料

したことを特徴とするものである。In order to solve the above problems, the method for repairing a composite material structure according to the present invention is a composite cutting tool in which a plurality of helical cutting edges made of diamond abrasive grains are radially provided on the conical surface of the tool body. It is characterized in that it is pressed against the damaged part of the material to scrape off the damaged part, and then filled with a repair agent of the same quality as the composite material structure.
また、本発明による切削工具は、工具本体の円すい面上

) indicates the presence of fM (M section 2) near the surface of the composite structure 1. In order to remove this damaged section 2, the cutting tool 3 according to the invention is used. As shown in FIGS. 2 and 3, the cutting tool 3 has a conical tool body 4, and a helical cut formed by sintering diamond abrasive grains is formed on the conical surface 5 of the body 4. Blade part 6
A plurality of these are arranged radially. A chip pocket 7 is formed between these adjacent cutting edges 6. The cutting tool 3 has a drive shaft 8 connected to a rotary drive tool such as an air tool, and is given rotational force. As shown in FIG. 1(b), the cutting tool 3 is positioned directly above the damaged part 2, and the damaged part 2 is scraped off using the cutting tool 3.
