摘要/Abstract

摘要： 塑料/金属直接成型技术是当前汽车轻量化技术的热点之一。采用酸碱处理和阳极氧化的表面处理方法，在铝合金表面制备了微-纳针尖状结构，通过自主开发的超声辅助热压技术成功实现了聚丙烯/铝合金直接复合成型，探讨了超声波参数对聚丙烯/铝合金复合界面结构与性能的影响，采用超薄切片、反溶解铝合金方法研究了界面形貌。拉伸-剪切试验结果显示，非超声压制件的界面拉伸-剪切强度为12.04 MPa，界面层平均厚度为6.47 μm，失效形式主要为混合失效；超声压制件的界面拉伸-剪切强度可达19.90 MPa，提高了65.3%，界面层平均厚度减小到为5.40 μm, 且聚丙烯与铝合金微纳表面形成良好的微观机械互锁结构，失效形式主要为内聚失效。试验表明，超声波辅助塑料熔体填充金属表面微-纳结构形成微观锚接效应，成功实现了塑料/金属直接成型。

Abstract: Direct plastic/metal molding technology is one of the research focuses in the vehicle lightweight technology currently. The micro-nano needle-like structure is prepared on the surface of aluminum alloy via chemical etching and anodization techniques, and the direct plastic/metal compound molding is successfully realized by a self-developed ultrasonic-assisted hot pressing technology. The influence of ultrasonic parameters on the interface structure and bonding properties of polypropylene/aluminum alloy hybrid is investigated. The interfacial morphology of the hybrid is displayed by using ultra-thin section technology and reverse dissolving method. The results show that the interfacial tension-shear strength of the non-ultrasonic pressing molded sample was 12.04 MPa, the average thickness of interfacial layer is 6.47 μm, and the tensile- shear failure is mainly presented as the mixed failure mode. As for the ultrasonic-assisted hot-pressed hybrid, the tensile-shear strength reaches 19.90 MPa, which is increased by 65.3% against the non-ultrasonic hot-pressed sample, and the average thickness of interfacial layer decreases to 5.40 μm. Moreover, a good micro-mechanical interlocking structure is formed on the interface surface of the ultrasonic-assisted hot-pressed hybrid, and the failure mode is mainly cohesive. It can be concluded in the experimental that ultrasonic helps plastic melt to enter the micro-nano structures on the metal surface and form micro-anchoring structures, which successfully realizes the direct plastic/metal integrated molding.

Key words: polymer/metal hybrid, ultrasonic-assisted hot-press molding technology, micro-nano mechanical interlocking structure, tensile-shear strength
