“…As the fibre architecture has a refraction index similar to that of the epoxy matrix, which amounts to 1.548–1.552, it is possible to use optical inspection to identify the inflicted damage [25]. A high-resolution optical camera Nikon D3100 was therefore used with an optical resolution of 4608×3072 pixels.…”

“…Especially in the aerospace industry, increasing economical demands combined with high performance requirements have led to substantial breakthroughs in the design and development of high-speed composite rotors, such as rotor blades [20,21,22,23]. The main focus has been directed toward the in-plane and out-of-plane dynamic behaviour, as well as the anisotropic material damping of undamaged composite rotors [24,25,26,27,28]. However, the gradual damage behaviour of composite rotors under unexpected loads has not been the main scope of the investigations of many researchers [29,30], and even less examined is the relation between gradual damage behaviour and the corresponding dynamic behaviour of composite rotors.…”

“…Therefore, a characterisation of the dynamic behaviour of rotors under different rotational speeds is an important factor for the optimal design and safe operation of rotors. Specifically, new experimental methods appropriate for the investigation of complex phenomena such as non-linear behaviour, gradual damage behaviour, internal friction and damping describing the structural behaviour of metallic and composite rotors are required [1,2]. These phenomena are not adequately considered in existing simulation models as they cannot be fully captured with existing measurement techniques not least due to a lack of suitable vibration excitation systems [3].…”
