    • PROBLEM TO BE SOLVED: To provide, in a case where a composite is damaged over the entire thickness direction thereof, a repair method based on access from one side thereof.SOLUTION: In a repair method of the present invention, a frustum-shaped range of a composite 10 is removed, and the composite 10 is adhered to a repair material 20 by performing a vacuum draw. The method of the present invention includes a removal step S2 of removing a damaged portion 11 from the front surface 10A side by punching through the thickness direction thereof in a state where a support wall 14 abutting inward along the diametrical direction from the peripheral edge of the vertex plane 32 of the frustum remains, a rear surface side sealing step S3 of sealing the rear surface 10B side by installing, on the support wall 14, a sealing plate 15 inserted, from the front surface 10A side, into a through-hole 12 formed as a result of removal, a repair material configuration step S5 of configuring, via an interposing adhesive AD, the repair material 20 on the composite 10 from which the frustum-shaped range thereof has been removed, and a vacuum draw step S6 of sealing and vacuum-drawing the front surface 10A side.
    • 要解决的问题:在复合材料在其整个厚度方向上损坏的情况下,提供一种基于从其一侧进入的修复方法。解决方案:在本发明的修补方法中,截头锥形范围 去除复合材料10,并通过进行真空拉伸将复合材料10粘附到修补材料20上。 本发明的方法包括一个去除步骤S2,该步骤S2是从沿着直径方向的内侧沿着直径方向从外侧边缘抵接的支撑壁14的状态,通过其厚度方向冲压而从前表面10A侧移除受损部分11 截头锥体的顶面32保持,后表面侧密封步骤S3通过在支撑壁14上安装从前表面10A侧插入到通孔12中的密封板15来密封后表面10B侧 作为去除的结果形成的修复材料配置步骤S5,通过中间粘合剂AD将修复材料20配置在去除其截头圆锥形范围的复合材料10上,以及密封 并真空拉伸前表面10A侧。
