Damping properties of epoxy resin/polyurethane (EP/PU) semi‐interpenetrating polymer networks (IPNs) were studied by the dynamic mechanical analysis (DMA) method. It shows that the semi‐IPNs have excellent damping properties at ordinary temperature. The maximum value of tan δ is about 1 when the weight composition of EP/PU is 70/30. Tensile tests also indicate that the system has good tensile strength and elongation at break at this ratio. The effects of structure on the properties of the semi‐IPNs are discussed. Applied to the cavitation corrosion resistant coating, the semi‐IPNs show good cavitation corrosion resistance. © 1996 John Wiley & Sons, Inc.
