Space conditions have a unique set of theories, which have many limitations on the technology of bringing human beings into space. Of course, rigorous space exploration is often the driving force of many new technological innovations. Insulation away from the atmosphere, in this case, can be as low as - 200 ° f in shadow and as high as 200 ° f in front of the sun.






Combining it with vacuum environment and adding extremely sensitive electronic and optical equipment to it, every design consideration is crucial to the process of sending objects into the spa, and the challenge is very arduous. However, the past success and failure experience will only increase people's desire for star vision.






Every design consideration is very important in the expensive attempt to send objects into space. One of these considerations (which may not seem important at first, but can lead to catastrophic consequences if not fully considered) is the choice of composite materials, which are used for bonding, insulation, damping, conducting and many other purposes. They are usually in close or direct contact with the main electronic optical equipment.






In general, any material used in space must have the following characteristics:






·Good radiation resistance






·Excellent ozone resistance






·Excellent thermal cycling resistance






Some of the materials that meet these requirements include silicone rubber, epoxy resin, polyurethane, etc., especially phenyl silicone rubber for aerospace materials has obvious advantages, because it can withstand extreme temperature in space, and can maintain good flexibility at very low temperature (other materials will harden and crack), and its elastomer characteristics can inhibit the emission vibration The adverse effects of sports. And the performance changes encountered in space flight, such as temperature changes, will lead to a surface shrinkage or hinder the propagation of electromagnetic waves and subatomic particles. The good high and low temperature resistance of phenyl silicone rubber will solve this problem.


Finally, although radiation in space can cause the properties of space materials to change similar to thermal aging, some special silicone materials, such as phenyl silicone rubber, have excellent radiation resistance, which are suitable for use under radiation conditions and still maintain good mechanical properties.
