NOVELTY - High temperature and corrosion resistant radar absorbing composite material comprises 10-20 pts. wt. nano graphene, 5-20 pts. wt. multi-walled carbon nanotubes, 10-15 pts. wt. nano-nickel oxide, 10-15 pts. wt. nano titanium dioxide, 15-20 pts. wt. ceramic substrate, 15-20 pts. wt. resin substrate, 5-15 pts. wt. reinforcing body, and 100-200 pts. wt. solvent. USE - Used as high temperature and corrosion resistant radar absorbing composite material. ADVANTAGE - The material expands range of electromagnetic wave absorption bands and enhances absorption rate using nano graphene, multi-walled carbon nanotubes, ceramic substrate and reinforcement as absorbents. The method improves temperature tolerance of high-temperature hidden materials by mixed setting of ceramic substrate and reinforcement, and increases hardness and electromagnetic wave absorption rate of high-temperature resistant materials using nano-nickel oxide and nano-titanium dioxide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing high temperature and corrosion resistant radar absorbing composite material, comprising mixing nano graphene, multi-walled carbon nano tube, ceramic substrate, resin substrate and reinforcing body under the inert gas, (ii) stirring the mixture at rotating speed of 300-400 revolutions/minute for 0.5-1 hour using grinder, filtering the grinded product by 150-mesh screen, and (iii) adding the filtered product into solvent, adding nano nickel oxide, nano-titanium dioxide for pre-mixing for 0.5-1 hour, using the alternating mode of mechanical stirring and ultrasonic mixing, uniformly stirring and mixing mixture to obtain product.
