NOVELTY - Graphene or stainless steel composite armor material comprises less than or equal to 0.03 wt.% carbon, less than or equal to 1.0 wt.% silicon, less than or equal to 2.0 wt.% manganese, less than or equal to 0.045 wt.% phosphorus, less than or equal to 0.03 wt.% sulfur, 10.0-14.0 wt.% nickel, 16.0-18.0 wt.% chromium, 2.0-3.0 wt.% molybdenum, balance iron and unavoidable impurities. USE - Graphene or stainless steel composite armor material. ADVANTAGE - The graphene or stainless steel composite armor material has high quality interface, high production efficiency and good for large-scale industrial production, and is process in simple manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene or stainless steel composite armor material, which involves: (A) preparing a nanometer sheet organic solution having a graphene layer number of less than 10 centrifugal nanometer disperser at a speed of 75-9000 revolution per minutes and a line speed of 85-115m/s organic solution graphene dispersions; (B) coating the graphene-coated stainless steel and spray the organic solution graphene dispersion onto a rotating stainless steel powder in a mixer using a sprinkler with a fan size of 60-280m; and (C) mixing in the mixer on the graphene-coated stainless steel powder for 20-100 minutes to obtain graphene and stainless steel composite armor materials.
