Solvent-free silicon-based ablation-resistant material

The invention provides a solvent-free silicon-based ablation-resistant material. The solvent-free silicon-based ablation-resistant material comprises 100 parts of liquid silicone resin, 0 to 20 parts of carbon fibers, 0 to 100 parts of silicon carbide, 0 to 10 parts of silica, 0 to 50 parts of metal oxide or silicate and 1 to 5 parts of a curing agent. The invention overcomes the problem that conventional silicone resin containing benzene solvents poses harm to human beings and pollutes environment when used as a matrix material for ablation of a solid rocket engine, the solvents need to be removed in the process of material molding and the period of material preparation is long; and the ablation-resistant material provided by the invention has high heat stability, good antioxidation performance and good ablation resistance, can realize casting or compression molding at normal temperature and is applicable to structural protection of aircrafts with complex structures and severe ablation. 种无溶剂型硅基耐烧蚀材料，包括液体硅树脂：
