Hygrothermal (HT) ageing is known to cause serious degradation in physical and mechanical properties of composite materials. This can result in variations in the dynamic response of a composite structure. The evaluation of dynamic properties over a period is a vital but demanding task. In this regard, non-destructive techniques can be economical and time-saving. In this study, carbon fibre-reinforced polymer (CFRP) composite has been considered to evaluate the effect of HT ageing. CFRP laminates were fabricated by hand lay-up using vacuum bagging process. The HT-ageing in CFRP was induced and accelerated by immersing specimens in a hot water bath at 80°C for different durations up to 500 h. Free vibration analysis and ultrasound scans were performed at different exposures of ageing to obtain a correlation between vibration damping characteristics and the ultrasound attenuation coefficient of CFRP subjected to HT-ageing. Based on the findings, the effect of ageing on vibration damping and on ultrasound attenuation has been observed. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
