摘要
为了改善橡胶的力学性能和阻尼性能,以橡胶、纤维和铅为原料设计了玻璃纤维增强铅网/橡胶阻尼复合材料,研究了不同玻璃纤维增强铅网铺层数量的横向玻璃纤维增强铅网/橡胶复合材料力学性能和阻尼性能,分析了其阻尼机制.结果表明,复合材料具有比橡胶更高的力学性能和阻尼特性,其刚度随铅网铺层数量的增加而提高,而阻尼损耗因子与铺层数呈非线性关系.复合材料中存在材料变形耗能、界面耗能、摩擦耗能等多种阻尼损耗机制.
A new damping composite composed of glass-fiber, lead and rubber was designed. Its mechanical property and damping property were studied and the damping mechanism was analyzed. Results show that the mechanical property and damping property of the composite are higher than those of rubber. The stiffness of the composite increases with the increase of the number of woven glass-fiber reinforced Pb-wires, however, its loss factor doesn' t increase linearly. It indicates that the damping of the composite comes from material damping, interfacial damping and energy dissipation caused by plastic micro-deformation of Pb.
