纤维增强铝合金层板的发展与应用

 本文介绍了最新研制的一种新型结构材料——纤维增强铝合金层板,该层板已引起许多西方飞机制造厂的注意。该材料兼取了复合材料和铝合金的优点,克服了各自的一些缺点。最引人注目的性能是它所具有的极好的抗疲劳和损伤性能。通过改变材料的组成和工艺过程,可以得到不同性能,满足某些特殊的用途。本文介绍两种典型的材料构型——芳纶纤维增强铝合金层板(ARALL)和R-玻璃纤维增强铝合金层板(GLARE)的研究过程、材料组成、性能和应用。最后讨论了今后研究所需要解决的问题。

DEVELOPMENT AND APPLICATION OF A FIBER REINFORCED ALUMINIUM LAMINATES

A new structure material family-fiber reinforced aluminum laminates (extended from term ARALL)was described in this paper, which is developed recently and has attracted attention of many west aircraft manufactures. The material family has combined the advantages of composite and alloy of aluminum and overcomes some disadvantages of them. The most attractive behaviour of this material family is its excellent resistance of fatigue and damage tolerance. Different configurations of the material family with different properties to meet some special usage can be achieved by changing its composition and procedure. The development, composition, properties and application of two typical configurations of the material family-aramid reinforced aluminum lami-nates(ARALL)and R-glass reinforced aluminum laminates(CLARE)are briefly introduced. Finally, the problems which need to be solved in the future development are also discussed.
