中空纤维自修复材料通过中空纤维与基体材料复合,当材料出现损伤时,中空纤维内部的修复剂可及时被“释放出来”,对材料损伤部位进行修复。与微胶囊自修复材料相比,中空纤维可承载较多的修复剂;中空纤维通过编织技术形成网络结构后加入基体材料,还能大幅度增强材料的力学性能。上述特点使得中空纤维自修复材料在材料的损伤修复设计方面有着广阔的发展前景。综述了中空玻璃管、中空玻璃纤维、中空聚合物纤维等自修复中空纤维的研究进展,并对存在的问题进行了总结。
Self-healing materials using hollow fibers can repair the damaged parts by releasing self-healing agent form hollow fibers.Comparing with self-healing materials using microcapsule,this method has advantages.One is that hollow fiber can contain more agent than microcapsules.The other is hollow fibers with weaving network structure can greatly enhance the mechanical properties of matrix materials.These features make the self-healing materials using hollow fibers with a good application future in terms of materials structure design.The hollow glass tube,hollow glass fiber,and polymer hollow fibers as healing agent container were briefly introduced.The existing problems were discussed,which will help to put forward the prospect of future research.
