の補修方法に関する。Description: TECHNICAL FIELD The present invention relates to a method for repairing a composite material structure, and in particular, repairs a damaged portion existing on the surface of the composite material by shaving the damaged portion with a diamond abrasive grain. The present invention relates to a method for repairing a composite material structure that is filled with a material.
一般に繊維強化プラスチック（FRP）の構造物の表面
もしくは内部に亀裂や損傷部が存在すると材料強度が低
下することから、その部分を補修する必要がある。その
ために、従来はハンドグラインダに豆砥石を取付け、損
傷部を台形状に削りとり、その部分に構造物と同質の材
料を充填して補修していた（特開昭56−63620および特
開昭60−89338号公報参照）。Generally, if there are cracks or damaged parts on the surface or inside of the structure of the fiber reinforced plastic (FRP), the material strength decreases, so that part needs to be repaired. For this purpose, a hand grinder was conventionally attached to a hand grinder, the damaged portion was ground into a trapezoidal shape, and the portion was filled with a material of the same quality as the structure for repair (JP-A-56-63620 and JP-A-SHO-63620) 60-89338).
しかしながら、上述した従来技術によると、被切削材
料がプラスチックの複合材料であるために砥石が目ずま
りをおこしやすく、消りとった面が凹凸となって剥離を
生じ、そのために接着性が良くなく空洞が生じるという
問題があった。However, according to the above-mentioned conventional technique, since the material to be cut is a composite material of plastic, the grindstone easily causes clogging, and the erased surface becomes uneven and peels off, which results in good adhesiveness. There was a problem that a cavity was created without it.
そこで、本発明は上記従来技術が有する問題点を解消
し、砥石が目つまりを起こすことなく、しかも削りとっ
た面に剥離を起こさないようにした複合材構造物の修理
方法を提供することにある。Therefore, the present invention provides a method for repairing a composite material structure that solves the problems of the above-mentioned conventional techniques and that does not cause clogging of the grindstone and does not cause peeling on the ground surface. is there.
上記課題を解決するために、本発明による複合材構造
物の修理方法は、工具本体の円すい面上にダイヤモンド

けられた切削工具を複合材の損傷部に押しあてて損傷部
を削りとり、その後に複合材構造物と同質の補修剤を充
填したことを特徴とするものである。In order to solve the above problems, a 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 formed by diamond abrasive grains are radially provided on a conical surface of a tool body. It is characterized in that it is pressed against the damaged portion of the material to scrape off the damaged portion, and then the repair material of the same quality as the composite material structure is filled.
また、本発明による切削工具は、工具本体の円すい面
上にダイヤモンド砥粒によるヘリカル状の切れ刃部の複
数個を放射状に配置したことを特徴とするものである。Further, the cutting tool according to the present invention is characterized in that a plurality of helical cutting edges formed by diamond abrasive grains are radially arranged on the conical surface of the tool body.
以下本発明による複合材構造物の修理方法を図面を参
照して説明する。A method for repairing a composite material structure according to the present invention will be described below with reference to the drawings.

とられる。1 (a), (b), (c), and (d) show each step of the method for repairing a composite material structure according to the present invention, and FIG. 1 (a) shows the surface of the composite material structure 1. This indicates that the damaged portion 2 is present in the vicinity. A cutting tool 3 according to the present invention is used to remove this damaged portion 2. As shown in FIGS. 2 and 3, this cutting tool 3 has a conical tool body 4, and the conical surface 5 of this body 4 has a helical shape formed by sintering diamond abrasive grains. Cutting edge 6
Are radially arranged. A chip pocket 7 is formed between these adjacent cutting edge portions 6. In such a cutting tool 3, the drive shaft 8 is connected to a rotary drive tool such as an air tool and is given a rotational force. First
As shown in FIG. 2B, the cutting tool 3 is located immediately above the damaged portion 2, and the damaged portion 2 is scraped off using the cutting tool 3.
次いで、第１図（ｃ）に示したように、補修穴９が形
