The invention discloses a carbon foam-based sandwich structure, a preparation method and a maintenance method thereof. The sandwich structure includes a carbon foam sandwich and a panel, the carbon foam sandwich is composed of one or more of resin-based, coal-based, and pitch-based carbon foams. It has the advantages of large quantity, high strength, impact resistance, good processability, stable physical and chemical properties, flame retardant, non-toxic, moisture-proof, wave-absorbing, and can be compounded with various functional materials. In different environments, the sandwich structure with prominent key functions and excellent comprehensive performance can be widely used in military and civil fields such as aerospace, automobile and ship, composite material manufacturing, construction, safety protection and so on. |
