Abstract.

The article describes research results of damping properties of carbon fiber reinforced plastics (CFRP). The effect of stress/strain levels on the damping value is studied. Research is conducted on flat samples (plates) with different lay-up schemes from 1-layered to 12-layered. The paper contains information about the modal and harmonic tests on the samples and their numerical modeling.

Keywords: modal analysis, harmonic analysis, finite element model, non-linear damping properties, carbon fiber reinforced plastics.
