A Review of Satellite Thermal Simulation Facilities in The Environmental Conditions of Earth's Orbits for Composite Structures

Components of the LEO environment consisting of high vacuum, ultraviolet radiation, thermal cycles, Atomic Oxygen, charged particles, electromagnetic radiation, micrometeorites, and space debris significantly degrade the material properties of polymer matrix composite materials. Therefore, in the design of space structures using composite materials, the possible deterioration of mechanical properties due to long-term exposure in LEO space environment should be carefully considered. Accordingly, a reliable understanding of the LEO environment in its effects on composite materials as well as investigating its properties is very important. The space simulator system under vacuum is designed with the aim of creating a standard environment with the ability to reach high vacuums and also the ability to create low temperatures, as well as to check the qualification of space components and research materials used in the satellite. These systems analyze the behavior of satellite components, evaluate their thermal balance and performance to ensure mission success and survivability.
