| Abstract: | The thermal conduction performance of carbon nanotubes / epoxy resin(CNTs/EP) composites materials were investigated quantificationally.The preparation method of CNTs/EP composites materials was obtained.Thermal conductivities of CNTs/EP composites materials were measured by hotdisk thermal constants analyser.Thermal conductivity of the two-phase composites materials could be predicted by the theoretical model.Finally,the numerical solution of the theoretical model could be obtained.The thermal conductivity of single-wall carbon nanotubes(SWCNTs),double-wall carbon nanotubes(DWCNTs) and multi-wall carbon nanotubes(MWCNTs) were 3980 W/(m.K),3580 W/(m.K) and 2860 W/(m.K) respectively. |
