摘　　要：本文根据材料性能互补原理，结合阻尼减振机制，设计并制备了一种（金属，无机纤维／橡胶）三元阻尼材料-玻璃纤维芯铅丝增强橡胶复合材料（GF／Pb／R）。研究了具有不同界面结合强度（弱、中等、强结合）的GF／Pb／R在-30℃～50℃、5Hz和27℃、1～50Hz两种条件下的存储模量和阻尼性能。结果表明，三种复合材料的力学性能均比橡胶高，其刚度随界面结合强度提高而提高；复合材料损耗因子按照界面弱结合、强结合和中等强度结合的顺序降低，其阻尼性能随温度的变化比橡胶平缓。A damping material, glass-fiber cored lead-wire （GF/Pb wire） reinforced rubber composite （GF/Pb/R）, was designed and prepared. The dynamic properties of GF/Pb/R with varied interface were tested under two conditions （ - 30℃ - 50℃, 5Hz and 27℃, 1 - 50Hz）. The mechanical property of the composite is higher than that of rubber. Its stiffness increases with the interface bond strength. However, its loss factor is the largest when the interface bond strength is weak, and is the least when the interface bond strength is medium, and is medium when the interface bond strength is strong. When the temperature increases, the damping property of GF/Pb/R doesn＇t decrease as obviously as that of rubber.
