US Patent 11781027 Printable mixed fillers epoxy composites

A composition of matter comprises at least 10 wt % epoxy functionalized two-dimensional shaped particles, carbon nanotubes in the range of 0.1 to 5 wt %, epoxy resin and a curing agent. A method of manufacturing a composition of matter includes mixing epoxy resin, carbon nanotubes and a solvent to produce a material, drying the material, and mixing the material with a curing agent to product the composition of matter. A method of printing a composition of matter includes producing the composition of matter by combining epoxy functionalized graphene, carbon nanotubes, epoxy base resin, and a curing agent, extrusion printing the composition of matter into a desired pattern, and curing the pattern.
