Damping and mechanical properties of composite composed of polyurethane matrix and preplaced aggregates
HighlightsTwo-stage manufacturing process and materials were proposed for high damping property.The new composite showed the damping ratio of 18.1%.The flexural strength of the composite is higher than that of normal concrete.The interfacial property between polyurethane matrix and aggregate was investigated by microscopic observation.
AbstractThis paper presents an experimental study of the damping and mechanical properties of a new composite produced by a two-stage casting process. Five mixtures according to the materials and manufacturing process were prepared. A series of experiments, including density, impact resonance, compressive strength, flexural strength, and uniaxial tension tests, were performed in order to characterize the damping and mechanical properties of the composite. The test results showed that the composite, which is composed of preplaced aggregate and polyurethane matrix, and produced by manufacturing process proposed in this study, showed significantly improved damping performance as well as better tensile behavior.
