In this paper, the multi-layered gradient materials consisting of polarized polymers and small molecules were prepared and the damping properties were studied by DMA. The predicted and experimental results showed that, it was possible to obtain damping material with broad efficient damping range by two-layered hybrid materials, the value in the middle of two peaks could be improved by increasing the number of layers of the multi-layered hybrids and there was a higher minimum value. On the other hand, with increased number of the layers of the multi-layered hybrid materials, the temperature dependence of could be improved. For five-layered gradient materials, it was almost rectangular transition range with values for the area under the linear curve. Thus, it would be feasible in theory and experiment to broaden the efficient damping range by multi-layered gradient materials based on organic hybrids, which provided a new approach and solid basis for developing high performance damping materials with a broad and high damping range.

AbstractIn this paper, the effects of multiwalled carbon nanotubes (MWCNTs) on the mechanical and damping properties of ultra-high performance concrete (UHPC) were investigated. The results show that the proper amount of MWCNTs can improve mechanical properties as well as the damping properties. For the mechanical properties, the compressive strength and flexural strength of the specimens increased with the increase of MWCNTs content in the range of 0~0.05% (mass ratio to cement). However, when the content of MWCNTs was more than 0.05wt.%, the mechanical properties of UHPC could not be improved continually because too many MWCNTs were difficult to disperse and agglomerated easily in UHPC. Similar laws also have been found for the damping property of UHPC. The loss factor of UHPC increased with the increase of MWCNTs content in the range of 0 ~ 0.05%. The incorporation of MWCNTs would introduce a large number of interfaces into UHPC, the friction and slip between interfaces were the main reasons for the improvement of the damping property of UHPC. However, when the content of MWCNTs was more than 0.05%, it was difficult to disperse effectively. As a result, the overall energy consumption efficiency of MWCNTs was decreased.
