CARBON FIBER FABRIC (made of carbon nanotubes) is already produced on a large scale at decreasing costs (from petroleum derivatives), however requiring several steps of heating at high temperatures and processing to form nanotubes, fibers, yarn and fabric.

GRAPHENE FABRIC (made of one atom thick carbon hexagonal network) has the potential for lower cost and higher performance if it is also produced on a high industrial scale (from renewable products such as carbon dioxide, methane and sugars), with direct cloth formation with several layers of two dimensional carbon, with the addition of resins to obtain various properties, with less expenditure of energy and simpler process.

GRAPHENE OXIDE (Cx Ox Hx) (mono carbon layer soluble in liquid/ink) production of graphene cloth from CO2 (carbon dioxide), CH4 (methane) and/or fructose (C6 H12 O6), obtaining oxygen (O2), hydrogen (H2), water (H2O) as sub-products. Graphene is impermeable to all gases and liquids, sealing vacuum, while graphene oxide is permeable to liquid and water steam, can be used for formatting with subsequent expulsion of oxygen and hydrogen. CH4 + O2 = CO2 + 2H2 (energy); CO2 + CH4
(+ argon) (500 Celsius) = 2C + 2H2 (CVD: Chemical Vapor Deposition in a metal substrate); 2H20 = 2H2+ O2 (electrolysis); C6 H12 O6 (200 Celsius) = 6C + 6H20 (autoclave, high pressure chamber, heated to 150-200 degrees Celsius for 1-2 hours to form graphene oxide layer).

GRAPHENE FABRIC PRODUCTION in high industrial scale with a graphene oxide layer of paint blasted with a supersonic spray (rocket nozzle) on a metallic substrate (copper, nickel or platinum) with high temperature and subjected to laser to expel oxygen/hydrogen. Formation of subsequent layers of graphene with subsequent addition of resin/epoxy to obtain different properties (conduction or not of heat and/or energy; flexibility/hardness). These same techniques could in theory be improved to transform carbon dioxide (CO2), methane (CH4) and fructose (C6 H12 O6) directly in graphene.



In the first method, graphene fabric is sewn and glued into Sandaeroblock shapes (sphere, cube, diamond, rectangular and triangular). Double cross graphene structure (four corners) containing halogen lamps is inserted in four parts connectable in the center. The air is heated and the shape inflated for resin application.

In the second method, more efficient, the step of production/sewing/inflation of the fabric is eliminated. Graphene is produced directly on an inflated nickel/copper fabric mold (with rounded corners) with supersonic (spray/rocket) or common(spray/brush/roller) application of graphene oxide. The kinetic force (impact), laser and/or high temperature will expel the oxygen and hydrogen atoms to leave only a layer of hexagonal network of carbon atoms.

Additional applications (or intercalated with other materials/resins) will form additional layers and close any fault in the network (Graphene with one layer of carbon atoms weighs 0.77mg/m2 and 1000 layers can form a network of less than 1g/m2 or less than 100g/m2 with resin, versus 300g/m2 of carbon fiber with resin). The resin is then applied, the double cross structure of halogen lamps is removed via 4 openings at the tips, the mold is deflated/withdrawn by the opening and the double cross structure is reinserted/reactivated to form solid monoblock without any sewing/glue.

The openings are sealed with air pump connected to air tube and electric wiring inside the double cross structure. The heated/pressurized air at 450 Celsius is partially removed to generate an internal density equivalent to 60% vacuum reducing/eliminating the block weight or generating floatation, depending on the size of the block and its altitude. The air can be almost completely evacuated at low pressure altitude, with the almost vacuum sustained by ultra lightweight rigid graphene structure. Vacuum/magnetic/mechanic sealed sliding doors/windows can be cut into the monoblocks.
