摘要:
为优化消防服外层氧化铝连续纤维制备工艺,提升消防服高温服役性能,采用溶胶-凝胶法,以氯化铝和硅溶胶为原料,制备前驱体溶胶及氧化铝连续纤维。从纤维晶相结构演变、表观形貌特征、不同烧结温度下纤维的常温与高温力学性能等角度,系统研究了烧结过程对纤维性能的影响机制,得到氧化铝连续纤维的最佳烧结温度为1 100 ℃,此时其断裂强度约为1 700 MPa,且在1 100,1 200,1 300 ℃下热处理2 h后强度保留率分别为97.3%,94.3%和65.0%; 氧化铝连续纤维的力学性能在1 300 ℃下可较长时间保持稳定。研究表明,通过精准控制烧结工艺,可有效提升氧化铝连续纤维的高温稳定性与力学性能,使其满足消防服严苛的高温防护需求。
Abstract:
To optimize the preparation process of alumina continuous fiber for firefighting clothing outer layers and enhance its high-temperature service performance, this study adopted the sol-gel method using aluminum chloride and silica sol as raw materials to prepare precursor sol and alumina continuous fibers. The study systematically investigated the influence mechanisms of the sintering process on fiber performance through analyses of crystalline phase evolution, morphological characteristics, and mechanical properties at both room temperature and elevated temperatures under various sintering conditions. The results reveal that the optimal sintering temperature for alumina continuous fibers is 1 100 ℃. At this temperature, their fracture strength is approximately 1 700 MPa. Furthermore, after heat treatment for 2 hours at 1 100 ℃, 1 200 ℃ and 1 300 ℃, the strength retention rates are 97.3%, 94.3% and 65.0%, respectively. The mechanical properties of the alumina continuous fibers remain stable for extended periods at 1 300 ℃. The research demonstrates that precise control of sintering parameters effectively enhances the high-temperature stability and mechanical properties of alumina continuous fibers, enabling them to meet the rigorous thermal protection requirements of advanced firefighting clothing.
