Application of polyimide foam stabilizer in spacecraft thermal insulation materials: Exploring the heat-resistant barriers of the boundaries of the universe

challenges and requirements of spacecraft insulation materials in the journey to explore the boundaries of the universe, the environmental conditions faced by spacecraft are extremely harsh. from high temperatures within the earth’s atmosphere to extreme low temperatures in outer space, to solar radiation and the impact of micrometeoroids, spacecraft must have strong thermal insulation to protect the safety of internal precision instruments and astronauts. therefore, the…
