Characterisation of the elastic and damping properties of traditional FML and FML based on a self-reinforced polypropylene

摘要

In this work, the characterisation of the elastic and damping properties of a traditional Fibre Metal Laminate (FML) and an FML based on a self-reinforced polypropylene (SRPP) was carried out. Both laminates were characterised in the frequency domain by means of a forced vibration test with a resonance technique where the Young's complex modulus was extracted. In addition to both FMLs, the aluminium employed in both laminates was characterised as reference material. Moreover, the transfer functions used for the characterisation process were included. The results showed that the FML based on a SRPP offers higher damping capacity than the traditional FML (C) 2015 Elsevier Ltd. All rights reserved.
