Physico-Chemistry of Elastomer Heat-Shielding Materials

Progress in rocket and space technique required the creation of a new types of materials, heat-shielding ones, which prevent decomposition of construction materials by high-temperature flows. This book discusses the problems of the creation of these materials, the main exploitational drawbacks of these coatings and the safety of such coatings.

Progress in rocket and space technique required the creation of a new types of materials, heat-shielding ones, which prevent decomposition of construction materials by high-temperature flows. During the last 40 years a great number of heat-shielding materials (HSM) were created for different exploitation regimes: Rubbers, foamy materials, asbo-, glass- and carbonic plastics, fireproofs, etc. In the late 50's the creation of a HSM for the internal surface protection of solid propellant rocket engines from high-temperature gas flows of combustion products (up to 4000k) became necessary. HSM's were also created for launching rocket parts and appliances. In most cases, HSM's are for a single use, because coatings are destroyed by highly enthalpic heating. This book discusses the problems of the creation of these elastic heat-shielding materials, the main exploitational drawbacks of these coatings and the safety of such coatings.
