One-way vacuum-pressure impregnation preparation method of carbon-carbon and ceramic-based composite material
The invention discloses a one-way vacuum-pressure impregnation preparation method of a carbon-carbon and ceramic-based composite material, which can sequentially discharge internal bubbles to the greatest extent, is particularly suitable for resin impregnation of large-thickness sample pieces, and meets the preparation requirements of large-thickness sample pieces such as throat liners and gas vanes of rocket engines. And meanwhile, a gradient structure formed by oxidation resistance, scouring resistance, ablation resistance and the like of the working surface of the sample piece can be conveniently realized, and the requirements of high performance and light weight are met. The method has the advantages of high impregnation efficiency, flexible gradient composition structure preparation, convenient large-thickness sample preparation and the like, the preparation period can be remarkably shortened, and the preparation cost is reduced.
本发明公开了一种碳‑碳和陶瓷基复合材料的单向真空‑加压浸渍制备方法，可以最大限度地顺序排出内部气泡，特别适宜大厚度样件的树脂浸渍，满足火箭发动机的喉衬、燃气舵等大厚度样件的制备需求，同时也可以方便地实现样件工作面的抗氧化，抗冲刷、抗烧蚀等梯度组成的结构，满足高性能轻质的要求。具有浸渍效率高，梯度组成结构制备灵活，大厚度样件制备方便等优点，可显著缩短制备周期，降低制备成本。
