Popis:	Composites / B 259, 110715 (2023). doi:10.1016/j.compositesb.2023.110715 In many applications metal foils are part of multifunctional composites exhibiting a wide range of (thermo-)mechanical fatigue loading. Data about low cycle fatigue of metallic foils subjected to tension-compression fatigueis sparse due to geometric limits. In this contribution, detailed information about design, tensioncompressionfatigue testing and data extraction of a layered sample are given. Fatigue failure of both copperand Pre-Preg are analysed using scanning electron microscopy and computed tomography. Numerical models areused to calculate the elastic and plastic strains for the copper foils within the composite sample, allowing acorrelation to the observed fatigue life.
