Graphene woven fabric (GWF) is synthesized by a template-based chemical vapor deposition (CVD) method. Compared to 2D graphene sheets, the GWF present unique morphological features and properties due to the lightweight graphene tubes integrated into a continuous network with a mesh configuration. Planar porous GWF/epoxy composites are prepared by directly infiltrating epoxy resin onto GWF and etching of the Ni template. These composites have a porous structure where the flexible and hollow graphene tubes are interconnected orthogonally in two perpendicular directions, totally eliminating the needs for careful dispersion and functionalization of graphene nanosheets to make composites. The composites exhibit excellent electrical conductivities, high mechanical properties and fracture toughness resulting from the well-designed graphene network structure. The effect of three different orientations of hollow graphene tubes are specifically investigated on complex fracture behavior and mechanical properties of the anisotropic composites. The new carbon material offers a potential as reinforcing filler for porous composites with interesting mechanical and multifunctional performance.
