Heat Resistance of Fiber Reactoplasts at High Temperatures

Abstract

Fibrous composite materials based on silica cloth were subjected to ablation tests using an arc plasma torch. The effect of the addition of corundum microspheres on the thermophysical characteristics and ablative properties of the material was studied. The addition of microspheres reduces the thermal conductivity, especially in the direction parallel to the fabric layers. Also, when corundum microspheres are added, the linear entrainment increases 2.5 times and the mass entrainment decreases by 16%. It is shown that during the test chemical reactions took place with the formation of new products.
