Carbon fiber composite ZrO2-C material and preparation method thereof
The invention discloses a carbon fiber composite ZrO2-C material and a preparation method thereof. The carbon fiber composite ZrO2-C material comprises, by mass, 22-28% of zirconium dioxide fine powder, 12-18% of graphite, 3-5% of metal silicon powder, 0-2% of boron carbide, 0.3-1.2% of carbon fiber, 5-8% of phenolic resin, and the balance of zirconium dioxide particles. The carbon fiber is added into the ZrO2-C material, so that the strength and the thermal shock resistance of the material are remarkably improved, the mechanical property and the thermal shock resistance of the material are improved under the condition that the carbon content is not increased, and the service life of a submersed nozzle is prolonged.
本发明公开了一种碳纤维复合ZrO2‑C材料及其制备方法，包括以下质量百分比的组分：二氧化锆细粉22～28％，石墨12～18％，金属硅粉3～5％，碳化硼0～2％，碳纤维0.3～1.2％，酚醛树脂5～8％，余量为二氧化锆颗粒。本发明在ZrO2‑C材料中加入碳纤维，显著提高了材料的强度及抗热震性，进而在不增加碳含量的情况下改善材料的力学及抗热震性能，延长浸入式水口的使用寿命。
