采用超声波振动的方法提高了胶粘剂对阳极氧化层的渗透，从而提高了阳极氧化预处理后碳纤维增强塑料/铝合金胶接接头的强度。通过正交试验设计了超声振动辅助胶接工艺，并进行了实验验证。通过对接头横截面形貌和元素分布的分析，研究了接头的强化机理。结果表明，超声振动辅助胶接工艺可进一步强化界面结合。研究的接头强度可达18.66MPa，比未超声强化的接头强度提高55%。超声波振动在粘合剂层中产生冲击波，导致朝向被粘物表面的高速粘合剂喷射，这使得界面粘合紧密并促进粘合剂渗透到阳极氧化层中。因此，通过形成更大的界面接触面积和更多的机械互锁结构，显著地提高了结合强度。
Ultrasonic vibration has been applied to improve the penetration of adhesive into the anodized layer, thereby enhancing the strength of carbon fiber-reinforced plastic/aluminum alloy bonding joints with anodizing pretreatment. The ultrasonic vibration-assisted adhesive bonding process was designed by orthogonal experiments, then verified experimentally. The strengthening mechanism was studied by analyzing the morphology and elemental distribution of the cross-section of the joint. The results show that the ultrasonic vibration-assisted adhesive bonding process can further strengthen the interfacial bonding. For the studied joints, the strength can reach 18.66 MPa, being 55% higher than without ultrasonic strengthening. The ultrasonic vibration creates shock waves in the adhesive layer, causing a high-speed adhesive jet toward the adherend surface, which makes the interfacial bonding tight and promotes penetration of the adhesive into the anodized layer. The bonding strength is thereby remarkably improved by forming a larger interfacial contact area and more mechanically interlocked structures.
