| Abstract: | The effect of moisture on the dynamic properties of hammer-milled glass-fiber-reinforced polyurethane was investigated. Similar investigations were also made on an unfilled polyurethane matrix for comparison. Moisture was found to increase the shear modulus at lower temperatures due to the formation of ice. At higher temperatures, however, shear modulus decreased due to the plasticizing effect of water. Moisture also modified the damping properties of the material. |
