摘　　要：讨论了氧化铝基连续陶瓷纤维的发展状况和试验室制备过程,初步获得了直径为(10～20)μm,单丝抗拉强度达到2300MPa的纤维。制备的纤维经热处理后有良好的柔软性,能适合纺织过程对纤维力学性能的要求。纤维热处理后发现有较多的断头,表明目前的拉丝速度与胶体的应力应变特性尚不匹配,需进行参数修正。The development and preparation,of alumina based continuous ceramic fibers are reviewed. The mechanical properties of （10-20） μm in diameter and 2 300 MPa in tensile strength were obtained at first step. Many breakpoint in the fiber bunch after heated has been observed, this express that the spinning speed didn＇t match to the shear rate of colloid in this period of work.
