| description | The invention discloses a carbon fiber felt and carbon nanotube/epoxy resin composite material and a preparation method thereof.The composite material is prepared by the steps that a carbon fiber felt serves as a template, after concentrated nitric acid modification and in-situ growth of ZIF-67 crystals are conducted, the carbon fiber felt with carbon nanotubes growing on the surface is obtained through the high-temperature catalytic pyrolysis and acid etching technology, and then the carbon fiber felt and the ZIF-67 crystals are obtained; and finally, preparing the carbon fiber felt and carbon nanotube/epoxy resin composite material by adopting a vacuum permeation epoxy resin process. A template pre-construction method is adopted, a carbon fiber felt framework is used as a template, adjacent carbon fibers are bridged and a heat conduction path is expanded by means of carbon nanotubes grown on the surfaces of the carbon fibers in situ, the contact thermal resistance between the carbon fibers is effectively re |
