Abstract:  In this work are presented the results of carbon reutilization from byproduct sources such as: black carbon, soots, biomass, PetCoke, etc. The byproducts had been processed by green methods to synthesized carbon nanostructures with outstanding mechanical properties ideal for composites. The synthesis methods are mainly milling and induction sintering with unique results demonstrating the successful synthesis of pristine blends of graphene, graphitic carbon, morphed graphene, among other nanostructures. All the process is conducted using physical and green methods such as milling and induction sintering. All milling conditions are carried at room temperature. The carbon nanostructures had been used to reinforce several types of composites such as ceramic, metals, polymers, biopolimers, etc. The resulting composites show outstanding mechanical behavior, including unprecedented elastic behavior under nano, micro and meso scale testing. Numerical simulations are used to further demonstrate and explain the atomic behavior of and its effect on composites. Our results demonstrate that rapid sintering can transform the as milled carbon into more complex nanostructures that act as effective reinforcements. To conclude we demonstrate some applications including biorecyclable and bio-compostable composites among others.
