高性能纤维复合材料在航空阻尼材料方面的应用

摘要

综述对金属和非金属阻尼材料用于飞机消音减振材料进行了比较,给出了阻尼减振用纤维材料的选择依据.分析了国外在减振阻尼用零件材料方面选用芳纶而不选用碳纤维的原因,提出了纤维增强复合材料中阻尼提高的改性途径.并将杂环芳纶中的F-12纤维和Armos纤维与对位芳纶Kevlar纤维进行了综合性能对比,可为用户选择应用阻尼用纤维材料提供参考.%This paper compared metal damping materials with nonmetal damping materials used as erasure and vibration-reduction materials in aircraft.The basis of choosing the fiber used in damping materials was given.The reason why damping materials overseas used aramid fiber rather than carbon fiber was analysed.The modified way to improve damping properties of the fiber reinforced composite was proposed.At the same time the comprehensive properties of F-12 fiber and Armos fiber which belong to heterocylic aramid fiber were contrasted with the properties of Kevlar para-aramid fiber,which can give a reference to users to choose and using the fiber as damping materials.
