Abstract
Nanocarbon materials have aroused great attention due to their unique extraordinary physical properties and electrical and thermal properties. Composites combining nanocarbon materials and resins together exhibit excellent mechanical properties and high viscoelastic damping as a result of more interfaces introduced into composites. The paper was mainly studying the effect of nano-material VGCF on the properties of structural damping composites prepared by the co-cured method with polyamide nonwoven fabric (PNF) coated with polyvinylidene fluoride (PVDF). The effects of VGCF on dynamic mechanical and damping properties of this composites were estimated through dynamic mechanical temperature spectra measured by DMA. In addition, the loss factor under different frequency, the conductive resistance in 3 directions and the impact toughness were studied through forced resonance experiment, electrical resistivity tests, pendulum impact experiments and observation of the microstructure with SEM. Results indicated that the damping and storage modulus could be improved by loading PVDF with VGCF on the nonwoven fabric with improvement of conductivity in 3 directions except impact toughness.
