Abstract:
Innovation design of the new ablation resistance materials should be focus on the source of the heat protection mechanism, because it is almost the high melting point or slow ablation rate to “endure” heat flow or prolong use life for the present traditional thermal protection materials, whose large density or ablation rate can not meet the strict requirement of future vehicle designer. The author designed a new material system—dissipation thermal protection materials—infiltrating reducing metal to graphite, whose dissipative agent dissipate heat and oxygen in ablation, and generate a kind of ceramic membrane to protect matrix.
