摘要: 通过研究玻璃纤维-铝合金层合板在盐雾环境下不同老化周期后的力学性能及复合材料层红外光谱,分析了层合板在盐雾老化条件下的性能变化。在加速盐雾老化条件下,树脂基体发生了降解,树脂-纤维界面及表面铝合金发生腐蚀破坏,随老化时间的延长,0°及90°层合板的拉伸、压缩及面内剪切强度均呈现出明显的下降趋势,90°层合板内部受到的损伤更为严重,盐雾环境会降低层合板内热固性树脂基体的交联程度,并破坏树脂-纤维及树脂-铝合金的界面,影响应力在玻璃纤维-铝合金层合板层间的传递,使材料力学性能发生衰减。

Abstract: The mechanism of salt spray aging of glass fiber-aluminum laminate was investigated by analyzing their mechanical properties and IR spectra. Under the condition of accelerating the salt spray aging, the inner matrix of the composite material was degraded, and the resin-fiber interface and the surface of the aluminum alloy corrosion damage occurred. With the extension of aging time, the tensile, compression and in-plane shear strength of 0 ° and 90 ° laminates showed a significant decreasing trend,while the laminate interface of 90°specimen suffered more serious damage. The degree of cross-linking of the thermosetting resin matrix inside the composite layer was reduced. Also, the resin-fiber and resin-aluminum interfaces were destroyed, consequently affecting the material internal stress transmission and the mechanical properties.

Key words: salt spray aging, glass fiber-aluminum laminate, interface
