Method for repairing carbon fiber toughened ceramic matrix composite component
The invention relates to a repairing method of a carbon fiber toughened ceramic matrix composite component. The method comprises the following steps: cleaning a damaged part, and then flaring the damaged part into a to-be-repaired part with a regular shape; designing a patch structure matched with the shape of the to-be-repaired part; a high-temperature adhesive is smeared on the connecting face of the to-be-repaired part and the patch structure, then the patch structure is installed on the to-be-repaired part in a physical connection mode, and the carbon fiber toughened ceramic matrix composite component provided with the patch structure is obtained; the patch structure and the to-be-repaired part are connected online through PIP, CVI and/or RMI; and preparing a coating on the surface of the treated carbon fiber toughened ceramic matrix composite component. The repairing method for the carbon fiber toughened ceramic matrix composite component is simple and effective, the formed patch is tightly combined with the material body, and the repairing method is suitable for repairing the carbon fiber toughened ceramic matrix composite component with the damaged body.
本发明涉及一种碳纤维增韧陶瓷基复合材料构件的修补方法。所述方法：清理破损部位，然后将破损部位扩口为具有规则形状的待修补部位；设计与待修补部位的形状相匹配的补块结构；在待修补部位与补块结构的连接面上涂抹高温胶黏剂，然后通过物理连接的方式将补块结构安装在待修补部位上，得到安装有补块结构的碳纤维增韧陶瓷基复合材料构件；通过PIP、CVI和/或RMI对补块结构与待修补部位进行在线连接；在经过上述处理后的碳纤维增韧陶瓷基复合材料构件的表面制备涂层。本发明提供的是一种简单、有效的碳纤维增韧陶瓷基复合材料构件的修补方法，所形成补块与材料本体结合紧密、适用于本体受损的碳纤维增韧陶瓷基复合材料构件修补。
