る。``Prior Art'' Conventionally, this type of high-temperature heat insulating structural material has been made of foam obtained by mixing micro hollow carbon bodies with foamable resin and foaming them, with the aim of improving the carbonization rate and decreasing the shrinkage rate. A method of producing carbon or graphite foam by firing is disclosed, for example, in Japanese Patent Publication No. 5836/1983.

It is disclosed in Japanese Patent No. 746.

空隙が集中してしまうという問題がある。"Problems to be Solved by the Invention" The heat insulating material disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 56-22694 is made by impregnating mineral fibers with thermosetting 4H resin and curing the resin. Although it is produced by pyrolysis at high temperature, it is difficult to uniformly create voids during the pyrolysis process because the shrinkage rates of mineral fibers and matrix are different, and voids are created at the interface between mineral fibers and matrix. The problem is that it becomes concentrated.

空隙にコールタール、クールピッチ、樹脂などの炭化可
能な物質を再付着させ、ついで再度焼成、炭化する緻密
化処理を十分に行なって空隙を埋めなければ、構造材と
しての強度を得ることがでなかった。In other words, voids concentrated at the interface between mineral fibers and matrix reduce compressive and flexural strength, and carbonizable materials such as coal tar, cool pitch, and resin are redeposited into these voids and then fired again. However, it was not possible to obtain the strength as a structural material unless the voids were filled by a sufficient densification process such as carbonization.
さらに、この緻密化処理は、熱伝導率を高める作用があ

あり、従って、構造材としての強度をもち、かつ低熱伝
導性を維持することは非常に困難なことであった。Furthermore, since this densification treatment has the effect of increasing thermal conductivity, it has a negative effect on its performance as a heat insulating material. Therefore, it has the strength as a structural material and maintains low thermal conductivity. It was a very difficult thing to do.

「発明の効果」
以上述べた如く、本発明によれば炭素繊維強化炭素板と
発泡体とが積層し一体化されているため、断熱材として
の低熱伝導性と構造材としての堅牢性を合わせもつ高温
断熱構造材料が得られる。Table 1 "Effects of the Invention" As stated above, according to the present invention, the carbon fiber-reinforced carbon plate and the foam are laminated and integrated, resulting in low thermal conductivity as a heat insulating material and robustness as a structural material. A high-temperature heat-insulating structural material with both properties can be obtained.
