Through the optimization of the connecting raw materials, a low cost high silicon fiber reinforced composite ceramic thermal insulation material is prepared by using cheap raw materials. The effects of impregnation and compounding process, heat treatment temperature and fiber weaving method on the material properties were analyzed. The corresponding process parameters were obtained. The experimental results show that the anti-heat insulation of the adhesive connection is destroyed in the heat flow experiment, and the anti-heat insulation structure connected by the fastener is verified by the heat flow test and the structural stability And thermal insulation properties are better, able to meet the needs of thermal protection on the surface of the projectile, and has good application prospects.
