The density of the fabricated samples was determined during the fabrication process. Density of the fabricated tungsten carbide based-epoxy resin composites was defined by the Eq. (1)23 (link). ρm=100cωρs+100-cwρl where ρm is the density of the mixture, cω is the concentration by weight in percent, ρl is the density of epoxy resin, and ρs is the density of filler powder.
