【 摘 要 】

In order to meet the thermal protection needs of aerospace, a composite material with low cost and good thermal protection effect was prepared. Boron phenolic resin is used as the matrix, and high silica glass fiber cloth is used as the reinforcing filler,the aluminosilicate mineral powder such as glass frit, feldspar powder, kaolin, talcum powder is a ceramic filler, and ceramic phenolic resin matrix composites were prepared by moulding method.The effects of different mineral powders on the properties of composites were investigated.The results show that with the increase of the amount of inorganic filler, the thermal conductivity of the material increases gradually, the high temperature weight loss rate is first increased and then decreased, and the minimum is reached when the filler content is 30%; The results of XRD analysis show that the inorganic filler in the material undergoes ceramization reaction at 1000° C to form a new material cristobalite, which effectively blocks the penetration of oxygen and heat into the material. The ceramic layer formed at high temperature makes the material flow at high temperature and high speed. The scouring resistance and oxidation ablation performance are improved, and it is expected to become a new type of heat-proof material.
