摘　　要：为了开发氧化铝纤维增强陶瓷基复合材料,提出连续氧化铝纤维用于2.5D结构织物时的可织性评价方法。通过模仿2.5D结构织物编织时的纤维受力状态,对纤维束织造过程损伤进行试验模拟,优选出合适的摩擦试验参数,并设计专用弯折工装对纤维束的耐磨、耐弯等性能进行评价。研究结果表明:通过评价纤维的摩擦损伤程度和弯折损伤程度,可以评价纤维用于2.5D结构织物的可织性;通过纤维/纤维摩擦实验进行可织性评价时,优选的参数为加载力0.35 N、张力0.3 N、摩擦频率3 Hz、摩擦时间80 s;同样参数下弯折,纤维断裂强力保持率越高,纤维的可织性越好;针对不同参数的编织结构而言,纤维的可织性是不同的。In order to develop alumina fiber reiforced ceramic matrix composites, the evaluation method of continuous alumina fiber weaveability for 2.5D structure fabric was proposed. The damage during the weaving process of the fiber bundle was simulated by imitating the fiber stress state during weaving of the 2.5D structure fabric, and the parameters for appropriate friction test were optimized. By designing special bending tooling, the performance of the fiber bundle such as abrasion resistance and bending resistance were evaluated. The research results show that by evaluating the degree of friction damage and bending damage of the fiber, the weaveability of the fiber for2.5D structure fabric can be evaluated. When evaluating the weaveability by fiber/fiber friction test, the preferred parameters are loading force of 0.35 N, tension of 0.3 N, friction frequency of 3 Hz, and friction time of80 s. Bending under the same parameters, the higher the retention of fiber breaking strength, the better the weaveability of the fiber. The weaveability of the fiber is different for the braided structure of different parameters.
