一种ZrB2-SiC-LaB6增强的碳/碳纳米复合材料及其制备方法
本发明公开了一种ZrB2‑SiC‑LaB6增强的碳/碳纳米复合材料及其制备方法，由ZrB2‑SiC‑LaB6前驱体凝胶与碳纤维复合后，经热处理制得；所述ZrB2‑SiC‑LaB6的分子式为(ZrB2‑20vol.％SiC)‑(10‑40)wt.％LaB6，其中ZrB2‑20vol.％SiC和LaB6的质量百分比为60‑90％：10‑40％。本发明利用ZrB2‑SiC‑LaB6作为涂层材料，涂敷于碳纤维编织体，经过热处理获得具有高抗热冲刷且抗氧化能力强的碳/碳复合材料。
The invention discloses a ZrB2-SiC-LaB6 reinforced carbon/carbon nano composite material and a preparation method thereof, the ZrB2-SiC-LaB6 reinforced carbon/carbon nano composite material is prepared by compounding ZrB2-SiC-LaB6 precursor gel and carbon fibers and then carrying out heat treatment, the molecular formula of the ZrB2-SiC-LaB6 is (ZrB2-20vol.% SiC)-(10-40) wt.% LaB6, wherein the mass percentage ratio of the ZrB2-20vol.% SiC to the LaB6 is (60-90%): (10-40%). ZrB2-SiC-LaB6 is used as a coating material and is coated on a carbon fiber woven body, and the carbon/carbon composite material with high thermal scouring resistance and high oxidation resistance is obtained through thermal treatment.
