本文提出了一种集成的被动阻尼方法在混合金属-碳纤维复合材料的结构应用。在该概念中，粘弹性材料嵌入在混合部件的接合区域中。为了检查连接强度，生产并测试了单搭接试样，并评估了所用材料组合、不同表面结构和不同工艺参数（即交联力矩）的影响。之后，在准静态测试中测试金属-CFRP混合物，以评估其连接强度和失效行为。动态循环拉伸试验与逐步增加的加载条件下进行，以确定试样的阻尼行为，并估计其疲劳性能。最后，这些结果进行了比较，以最先进的金属-CFRP混合与铆钉连接两种材料。
This paper presents an integrated passive damping approach in hybrid metal-CFRP parts for structural applications. In this concept a viscoelastic material is embedded in the joint zone of the hybrid component. To examine the connection strength single-lap-joint specimens were produced and tested and the influence of the used material combinations, different surface structures, and different process parameters i.e. the moment of cross-linking were evaluated. Afterwards, the metal-CFRP hybrids were tested in quasi-static tests to assess their connection strength and failure behaviour. Dynamic cyclic tensile tests with step-wise increased loading conditions were performed to determine the specimens damping behaviour and to estimate their fatigue performance. Finally, these results are compared to a state of the art metal-CFRP hybrid with rivets connecting both materials.
