Interpenetrating polymer network composites containing polyurethanes designed for vibration damping

The paper is a literature review concerning the interpenetrating polymer network (IPN) composites containing polyurethanes that can be used for vibration damping in marine vehicles. The effects of filler introduction on damping, mechanical and thermal properties of IPN are compared. The addition of filler affects all relevant properties, in dependence on the filler type and quantity. Damping enhancement is achieved by introduction of each of studied fillers. The ability to optimize IPN structure and filler incorporation provides a way to obtain a material with desired features.
