Abstract A novel assembling technique based on additive manufacturing and materials joining principles has been introduced for layered metal-polymer hybrid structures. The AddJoining technique produces layered hybrid structures, using polymer 3D printing methods. The feasibility of the technique was demonstrated using fused deposition modeling for single-lap joint configuration. Microstructure and mechanical strength of the joints were studied using two combinations of materials; aluminum 2024-T3 with acrylonitrile butadiene styrene and aluminum 2024-T3 with alternate layers of polyamide-6 and carbon-fiber-reinforced polyamide-6. The latter reached an average ultimate lap-shear strength of 21.9 ± 1.1 MPa, showing 19% superior performance to the adhesively bonded joints. This exploratory investigation showed the potential of AddJoining to produce metal-polymer layered structures.

AddJoining：一种用于分层金属-聚合物混合结构的新型增材制造方法

摘要 本文介绍了一种基于增材制造和材料连接原理的新型组装技术，用于层状金属-聚合物混合结构。AddJoining 技术使用聚合物 3D 打印方法产生分层混合结构。使用单搭接接头配置的熔融沉积建模证明了该技术的可行性。使用两种材料组合研究了接头的显微组织和机械强度；带有丙烯腈丁二烯苯乙烯的铝 2024-T3 和带有聚酰胺 6 和碳纤维增强聚酰胺 6 的交替层的铝 2024-T3。后者达到了 21.9 ± 1.1 MPa 的平均极限搭接剪切强度，表现出比胶粘接头优越 19% 的性能。
