| Abstract Scope |
Fiber metal laminates (FML) were introduced to decelerate crack development compared to e.g., aluminum in the aerospace industry. The ever-increasing demand for sustainability (including recyclability and long-term use) leads to the search for alternatives to thermoset variants. Thermoplastic-based FML enables improved possibilities in formability and shorter production times. Knowledge about the fatigue properties is indispensable for fatigue life estimation and thus part design, but is yet not sufficiently acquired. In this study, 3D digital image correlation is used combined with electrical resistance measurement for precise in situ monitoring of fatigue cracks and deformation in a thermoplastic-based FML, consisting of glass and carbon fiber-reinforced polyamide 6 and AA6082 sheets. Correlations of the measurement data to high-resolution information about the interlaminar damage, gathered by computed tomography and microscopy, are used to establish a short-time testing and measurement procedure for in-depth fatigue characterization of FML up to the very high cycle fatigue regime. |
