Alumina fiber reinforced alumina-carbon slide plate and preparation process thereof
The invention relates to an alumina fiber reinforced alumina-carbon sliding plate and a preparation process thereof, alumina fibers are added and uniformly dispersed in a matrix to form an organic composite whole, so that the load borne by a matrix material is reduced, and crack propagation free energy is consumed; meanwhile, Si and SiO2 in the matrix are subjected to high-temperature treatment and in-situ reaction to generate a mullite phase, a high-strength net-shaped structure is formed, the mechanical property of the material is improved, and the thermal shock resistance of the material is improved.
本发明涉及一种氧化铝纤维增强型铝碳质滑板及其制备工艺，通过加入氧化铝纤维，均匀分散到基质中，形成有机复合整体，减少基体材料承担的负荷，消耗裂纹扩展自由能；同时与基质中的Si和SiO2经高温处理原位反应生成莫来石相，形成高强网状结构，提高材料的力学性能，改善材料的热震稳定性。
