DMA of TPU Films and the Modelling of Their Viscoelastic Properties for Noise Reduction in Jet Engines

DMA of TPU Films and the Modelling of Their Viscoelastic Properties for Noise Reduction in Jet Engines

Due to current developments in jet engine design, the acoustic performance of conventional acoustic liners needs to be improved with respect to lower frequency spectrums and broadband absorption. In this context, the present study aimed to determine the viscoelastic material properties of a thermopl...
