In general, plastic sheet displays vibration-damping by converting vibration energy into thermal energy. Laminated steel plates were prepared by putting a plastic sheet between two steel plates. The extent of vibration-damping of the laminated steel plate was evaluated for two types of plastics by measuring the loss factor. The resins investigated were acrylonitrile (A)-styrene (S)-butyl acrylate (B) terpolymer and methyl methacrylate (M)-butyl acrylate (B) copolymer. We prepared eight kinds of specimens having different butyl acrylate contents. A cantilever method was adopted for obtaining frequency response spectra, from which the loss factor was derived according to ASTM-E756. Laminated steel plates with AS-B terpolymer gave the maximum loss factor at temperatures above 100℃. The factor was as high as 0.5 at 40℃ for the plate prepared from the M-B copolymer having butyl acrylate of 54 mol %. The plates with M-B copolymer are expected to be very useful for vibration-damping near room temperature.
