Development and validation of a test facility for bending corrosion fatigue of hybrid laminates

Abstract

In this article, the development of MoBeMeG, a modular device for bending-corrosion-fatigue investigations and variable specimen geometry in corrosive media with galvanic isolation between the test chamber and the test system, is presented. The main application is the investigation of hybrid laminates with high potential for galvanic corrosion, e.g., aluminum ∪ carbon fiber–reinforced plastics, focusing on the description of failure mechanisms and failure evolution at the interface under the influence of bending-corrosion-fatigue loading. The anvil distances are adjustable for the application of varying specimen geometries while retaining the full functionality of the test chamber and securing a full flexible testing possibility without the necessity of new constructions. The test engineering development results in considerable time savings as well as unparalleled efficiency enhancement in terms of bending-corrosion-fatigue performance assessments.
