Space Engineering - Thermal design handbook - Part 7: Insulations

There are 3 main categories of insulators used in spacecrafts:
1. foams: organic and inorganic;
2. fibrous insulations: for internal and external insulation and for high temperature environments
3. multilayer insulations (MLI): layers of radiation reflecting shields.
Properties, thermal behaviour and application areas of the insulation materials used in spacecrafts are detailed in this Part 7.
The Thermal design handbook is published in 16 Parts
