摘要

金属-塑料混合材料（MPHs）因其高比强度而获得广泛应用，有利于工业产品的轻量化设计。这项工作旨在定制mph的界面状态，以提高与各种应用场景相关的拉-推载荷下的结合强度。为了系统地揭示微图案尺寸、分布、形貌和化学键等界面影响因素，采用飞秒激光处理铝钛合金与聚苯硫醚通过注射成型的方式结合形成MPHs (Al/PPS和Ti/PPS)，并对其拉载荷和推载荷剪切强度进行了研究。铝合金表面形成了有趣的花菜状深图案，具有激光诱导的周期性表面结构，具有较高的抗剪强度，而钛合金表面则出现了浅而光滑的波状图案。而在相同粒径/分布的情况下，Ti/PPS的抗剪强度显著高于前者（最大10.5 MPa）。此外，在拉力和推力载荷下，临界微图案深度dc1为~ 40 μm， dc2为~ 300 μm。这项研究为设计和制造各种应用的轻型mph提供了指导方针。

Femtosecond-laser tailoring interfaces of injection molded metal-plastic hybrids: shear strengths and failure modes under pull-push loadings

Metal-plastic hybrids (MPHs) gain wide applications thanks to their high specific strength beneficial to lightweight design for industrial products. This work aims to tailor MPHs’ interface states in order to improve bonding strengths under pull-push loadings associated with various application scenarios. To systematically reveal the interface influencing factors such as micro-pattern size, distribution, morphology, and chemical bond, femtosecond-laser treated aluminum and titanium alloys were bonded to polyphenylene sulfide to form MPHs (Al/PPS and Ti/PPS) via injection molding, and both pull and push-loading shear strengths were investigated. Interesting cauliflower-like deep patterns with laser-induced periodic surface structures formed for the aluminum alloy resulting in higher shear strength, while shallow and smooth wave-like patterns appeared for the titanium alloy. However, with the same micro-pattern nominal size/distribution, Ti/PPS possessed significantly higher shear strength (Max. 10.5 MPa). Moreover, critical micro-pattern depths, d_c1 of ∼40 μm, and d_c2 of ∼300 μm were determined under the pull and push loadings, respectively. This study provides guidelines for designing and manufacturing lightweight MPHs for various applications.
