Claims
- 1. A method for producing a heat insulating material comprising steps of;agitating silica or alumina fiber, SiC whisker and a solution of polyester resin in water to obtain a slurry; pouring said slurry into die frame to dehydrate it and to obtain an accumulated inorganic fiber plate; drying said plate to obtain a core member; putting said core member between a high temperature side skin member made of alumina fiber cloth and a low temperature side skin member made of glass cloth; covering side wall parts of the core member by the high temperature side skin member; and tying together said high temperature side skin member, said low temperature side skin member and said core member by using thread made of heat resisting inorganic fiber.
- 2. A method according to claim 1, wherein said core member comprises 100 weight parts of silica or alumina fiber and 15 to 50 weight parts of SiC powder and/or whisker.
- 3. A method according to claim 1, wherein said heat insulating material had a thermal conductivity of 0.035 W/mK or 0.041 W/mK at 800° C. in an atmosphere of 0.01 Torr.
