对铝合金表面经化学法、机械-化学法或化学-阳极氧化法预处理后,再经铺设玻璃纤维布、浸渍环氧树脂、静置固化等过程,获得玻璃纤维-铝合金叠层板;观察分析了铝合金表面和叠层板界面微观形貌,并测试叠层板力学特性。结果表明:3种预处理方法相比较,铝合金表面微孔孔径依次增大、孔数依次增多、分布依次更均匀;化学-阳极氧化法处理的铝合金制备的叠层板界面缺陷少、力学特性好。
After pretreatment of the surface of the aluminum alloy by chemical, mechanical-chemical or chemical-anodic oxidation methods, glass fiber-aluminum alloy laminate is obtained by laying fiberglass cloth, impregnating the epoxy resin, standing and curing, and the like; The microstructure of the interface between the aluminum alloy and the laminate was observed and analyzed. The mechanical properties of the laminate were tested. The results show that compared with the three pretreatment methods, the pore diameters of the aluminum alloy surface increase in turn and the number of pores increases in sequence and the distribution is more uniform. The interface defects of the aluminum alloy prepared by the chemical-anodic oxidation process are less and the mechanical Good features.
