表面处理对铝合金粘接修理性能的影响
EFFECT OF SURFACE TREATMENT ON ADHESIVELY BONDED REPAIR OF ALUMINUM
摘要
Abstract
GFRP adhesive repaired damage aluminum,aluminum alloy surface was treated with different concentrations of the silane coupling agent KH550,KH560,and compared with non-treated aluminum sample.The repair effect was studied by tensile and humidity test.The results showed that two kinds of coupling agent KH550,KH560 have simular effect on repair sample.After treated with coupling agent of 1％ ～ 2％ concentration,the repaired samples have a high initial strength and the heat-resistant properties are also improved.Humidity treatment has significant adverse effects on the mechanical properties,and the damage of hygrothermal environment for aluminum-layer interface is stronger than layer-GFRP interface.The decrease of adhesive strength between aluminumlayer interface is the main reason of sample performance degradation.关键词
