A Review of Experimental and Comparative Study of Cork-Based Nanocomposite Dampers with Normal Dampers in the Field of Construction

Abstract

Cork products have an increasing demand for vibration damping systems due to their good vibration isolation behavior as well as their eco-friendly and sustainable properties. Cork is a lightweight, natural material made from the bark of the Quercus Suber L. tree, which can be found in Portugal's forests. The principal application is wine stoppers, but due to its unique thermal and vibration insulation and acoustic characteristics, it is now commonly found in construction and aeronautic applications. Nowadays, the urge to have lightweight and environmentally friendly materials with improved mechanical properties is increasing. As technology and ideas emerge, composite materials evolve with different elements to test different approaches. This paper reviews the possibility of using granulated cork and other nanomaterials as reinforcement and the various preliminary tests that are performed to characterize the dynamic properties of the composite with a view to assessing its ability to attenuate vibration in the concrete material. The same experimental results were compared with the normal dampers without cork and nanomaterials.
