阳极氧化工艺对纤维-铝合金层板力学性能的影响

通过改变铝合金表面阳极氧化工艺参数, 研究了阳极氧化电压和时间对玻璃纤维-铝合金(GLARE)层板抗拉强度和层间剪切强度的影响。通过SEM观察了铝合金表面Al₂O₃多孔膜和层板断面形貌, 分析了铝合金/树脂胶接界面对层板力学性能的影响。结果表明, 阳极氧化电压为20 V时, GLARE层板抗拉强度和层间剪切强度随着阳极氧化时间延长而增大, 在20 min时出现最大值, 继续延长阳极氧化时间, 层板强度随之下降; 阳极氧化时间为20 min时, GLARE层板抗拉强度和层间剪切强度随着阳极氧化电压增大而增大, 在20 V时出现最大值, 继续增大电压, 强度随之下降。

Effect of anodizing process on the mechanical properties of glass fiber reinforced aluminum laminates

The influence of varying anodizing voltage and time on the tensile strength and interlaminar shear strength(ILSS) of glass fiber reinforced aluminum (GLARE) laminates was investigated. The topographic information of Al₂O₃ anodic film and fracture surface on laminates was obtained by SEM. The effect of aluminum/resin adhesion on the mechanical properties of GLARE laminates was discussed. The results show that tensile strength and interlaminar shear strength of laminates increase with prolonging the time of anodizing at 20 V, and reach maximum at 20 min, then decrease with extending the anodic time. The tensile strength and interlaminar shear strength of laminates increase with raising the voltage of anodizing at 20 min, and reach maximum at 20 V, then decline with increasing the anodic voltage.
