Abstract
People discover the synergistic effect of graphene and carbon nanotubes on heat conduction in graphene carbon nanotubes / epoxy resin hybrid composites. In this article we added them into the phenolic resin and test the thermal conductivity. We found the thermal conductivity was increased by 6.5% in the phenolic resin by adding 0.45wt% graphene and 0.15wt% single wall carbon nanotubes (maintain the mass ratio 3:1). So if graphene and carbon nanotubes are added in proportion, thermal conductivity of phenolic resin will be improved significantly which is better than only carbon nanotubes or graphene.

People discover the synergistic effect of graphene and carbon nanotubes on heat conduction in graphene carbon nanotubes / epoxy resin hybrid composites, which has provided a new idea for the study of high thermal conductivity polymer composites
Seeing the thermal conductivity from the experiment, we found the addition of graphene will increase the thermal conductivity, adding carbon nanotubes alone will make the thermal conductivity has a small increase, while adding graphene and carbon nanotubes can greatly improve the thermal conductivity
Summary
Graphene and carbon nanotubes are good conductors for electricity and heat because of their special structure. There are many useful way to produce Graphene [1] and carbon nanotubes [3, 4]. They are very suitable to produce resin composite materials. People discover the synergistic effect of graphene and carbon nanotubes on heat conduction in graphene carbon nanotubes / epoxy resin hybrid composites, which has provided a new idea for the study of high thermal conductivity polymer composites. In the case of no change in the interface, the thermal conductivity of graphene and carbon nanotubes can significantly improve the thermal conductivity of epoxy resin composites. Carbon nanotube nanocomposites have attracted wide attention, most of them are carbon nanotube polymer composites, there are few about the metal and nanotube reinforced composites with ceramic matrix
