Repair method of continuous oxide fiber reinforced oxide ceramic matrix composite material
The invention relates to the technical field of oxide fiber reinforced oxide ceramic-based composite materials, and particularly discloses a repair method of a continuous oxide fiber reinforced oxide ceramic matrix composite material. The repair method comprises a composite material surface damage repairing method. The damage repairing method comprises the following steps: cleaning invalid damaged tissues at a damaged part; preparing a repairing material; filling the damaged part with the repairing material, compacting, and drying and sintering byadopting portable heating equipment to complete preliminary repairing; brushing the preliminarily repaired surface with slurry through a brush, then drying, repeating brushing-drying, and compacting after brushing-drying is completed; and sintering and polishing to complete composite material surface damage repairing. According to the repairing method of the continuous oxide fiber reinforced oxide ceramic matrix composite material, the repairing process is simple, a repairing tool and heating equipment are simple and portable, the repairing period is short, and the repaired composite material is complete in internal structure and good in mechanical property and shows good function restoration.
本发明涉及氧化物纤维增强氧化物陶瓷基复合材料技术领域，具体公开了一种连续氧化物纤维增强氧化物陶瓷基复合材料的修复方法，包括复合材料表面损伤修复方法，包括以下步骤：清理受损部位无效的受损组织；制备修补材料；将修补材料填充到受损部位并压实，采用便携式加热设备进行干燥、烧结，完成初步修复；采用刷子在初步修复表面刷涂浆料，然后干燥，重复刷涂‑干燥，完成后致密化处理；烧结、打磨，完成复合材料表面损伤修复。本发明的连续氧化物纤维增强氧化物陶瓷基复合材料的修复方法，修复过程简单，修复工具和加热设备简单便携，修复周期短，修复后的复合材料内部结构完整，力学性能良好，表现出较好的功能恢复性。
