The conducted research suggests possibility of replacing extruded polystyrene with a renewable cork-based material in laminated composite structures. Different fractions of the cork-based material of a composite laminate have been applied. The composites have been tested employing a hammer-focused vibration method. Conforming to obtained results, the cork-based material of smaller fraction has damping properties similar to those of the extruded polystyrene composite. Integrating cork into the structure of the composite has the opportunity to develop a more eco-friendlier and sustainable product and to improve the adaptive properties of passive control systems used for vibration damping applications operating in the middle and high frequency zones.
