Preparation method of alumina fiber reinforced ceramic composite material containing mullite interface layer
The invention discloses a preparation method of an alumina fiber reinforced ceramic composite material containing a mullite interface layer, and relates to the technical field of alumina fiber reinforced ceramic composites.The preparation method comprises the steps that mullite sol is prepared, alumina fiber cloth is pretreated, and then forming, dipping, drying and heat treatment are conducted to obtain the alumina fiber reinforced ceramic composite material containing the mullite interface layer. And circularly densifying to obtain a finished product of the alumina fiber reinforced ceramic matrix composite containing the mullite interface layer. The mullite interface layer is formed between the alumina fiber and the oxide matrix, so that the bonding strength between the fiber and the matrix can be effectively reduced, the toughening and reinforcing effects of the fiber are exerted, and the mechanical property of the composite material is improved. The preparation method is simple and feasible.
本发明公开一种含莫来石界面层的氧化铝纤维增强陶瓷复合材料制备方法，涉及氧化铝纤维增强陶瓷复合材料技术领域，通过制备莫来石溶胶，氧化铝纤维布预处理，再通过成型，浸渍，干燥和热处理，循环增密后得到含莫来石界面层的氧化铝纤维增强陶瓷基复合材料成品。本发明通过在氧化铝纤维与氧化物基体之间形成一层莫来石界面层，能够有效降低纤维与基体之间的结合强度，发挥纤维的增韧增强作用，提高复合材料的力学性能。制备方法简单易行。
