The research status of phenolic resin and silicone resin as heat protection materials is expounded. In this paper, the structural modification and addition modification of phenolic resin matrix were reviewed. The research progress of metal elements, silica fume and ceramic modified phenolic resin was introduced. At the same time, a brief analysis of the research on silicone resin as thermal protective material was also made. And prospects of this kind of evolvable ceramic new type of resin-based thermal protection material development prospects.
