Abstract:

The creation of the thermal isolation experimental samples of the sandwich type composition materials working at high temperature (about 10000C) had been developed.It was elaborated the technology of thermal isolating materials, for which the perlite, fireproof clay and ortho-phosphoric acid were used. For manufacture of the different types of sandwich panels the high temperature and strength fiber wears, zircon oxide and talk were used. The testing on strengthening of the developed samples shown that their strength limit on bending is about 2.5 MPa, which is 4-5 times higher than for nonsandwich analogues of the same type. It was developed a model of the element of wall made from sandwich material, on the basis of which it was created three types composition sandwich panel and their effectiveness of thermal isolating properties were studied with use of the own working at 11000C. It was established experimentally that at temperatures about 10000C the temperature of outside “cold wall” was no more than 65-900C.
