Repairing method of carbon/carbon composite material
The invention belongs to the technical field of material repairing, and particularly relates to a repairing method of a carbon/carbon composite material. The repairing method of the carbon/carbon composite material comprises the following steps: mixing inorganic powder with high-carbon-residue resin to obtain coating slurry; coating the defect position of the carbon/carbon composite material withthe coating material, and sequentially carrying out curing, carbonization and polishing; and performing chemical vapor deposition on the surface of the polished product through an alkane gas carbon source, and forming a deposition coating on the surface of the polished product. The repairing method is beneficial to ensuring the surface smoothness and strength of the carbon/carbon composite material, and repairing and improving the quality of the carbon/carbon composite material. The embodiment shows that the repairing method can improve the integrity of the carbon/carbon composite material, sothat the material meets the basic physical and chemical properties, and the defective rate is effectively reduced.
本发明属于材料修复技术领域，特别涉及一种碳/碳复合材料的修复方法。本发明提供了一种碳/碳复合材料的修复方法，包括以下步骤：将无机粉与高残碳树脂混合，得到涂敷浆料；将所述涂敷料涂敷在碳/碳复合材料的缺陷位置，依次进行固化、碳化和打磨；利用烷烃类气体碳源对打磨产品表面进行化学气相沉积，在所述打磨产品表面形成沉积涂层。本发明提供的修复方法有利于保证碳/碳复合材料表面平整性和强度，修复提高碳/碳复合材料的质量。实施例表明，本发明提供的修复方法可以提升碳/碳复合材料的整体性，使材料满足基本的物化性能，有效降低残次品率。
