Raumfahrtfolien

Raumfahrtfolien, also known as space films or aerospace films, are specialized materials used in the construction and protection of spacecraft, satellites, and other spaceflight applications. These films are engineered to withstand the extreme conditions of outer space, including vacuum, radiation, and wide temperature fluctuations. Their properties are crucial for the longevity and functionality of space missions.

Commonly used Raumfahrtfolien include Mylar (polyethylene terephthalate, PET) and Kapton (polyimide). Mylar is often used for thermal insulation, forming multi-layer insulation (MLI) blankets that reflect heat and protect sensitive components from solar radiation and the cold of deep space. Its reflective properties are key to maintaining stable internal temperatures. Kapton, on the other hand, is known for its excellent thermal stability and electrical insulation properties. It can withstand high temperatures and is often used for wiring insulation and flexible circuits within spacecraft.

Other advanced polymers and composite materials are also employed, often with specific coatings or treatments to enhance their performance. These can include materials designed for radiation shielding, protection against atomic oxygen erosion in low Earth orbit, or improved optical properties for solar sails and scientific instruments. The selection of a specific Raumfahrtfolie depends heavily on the mission requirements, the specific environment the component will encounter, and the desired functional characteristics. The development and application of these advanced films are critical to enabling successful space exploration and utilization.
