Space conditions have a unique set of theories, which have many limitations on the technology of bringing human beings into space. Of course, strict space exploration is often the driving force for many new technological innovations. Insulation far from the atmosphere in this case, the temperature in shadow can be as low as -200 ° F. Up to 200 when facing the sun ° F。


It is very important to combine it with vacuum environment and add extremely sensitive electronic and optical equipment to it. Every design consideration is very important and challenging for the process of sending objects into hot springs. However, the past success and failure experience only increases people's desire for star vision.


Every design consideration is very important in the expensive attempt to send objects to space. One of these considerations (which may not seem important at first, but which can lead to catastrophic consequences if not considered well) is the selection of various composite materials that are used for other purposes such as bonding, insulation, damping, and conductivity. They are usually directly or directly in contact with the main electronic optical equipment.


Generally, 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 some of these requirements include silicone rubber, epoxy resin, polyurethane, etc., especially phenylsilicone rubber used in aerospace materials, which have obvious advantages because they can withstand extreme temperatures in space and maintain good flexibility at very low temperatures (other materials will harden and break), The elastic properties of the system can restrain the bad effect of emission vibration. And the performance changes encountered in space flight, such as temperature change, may cause a surface contraction or hinder the propagation of electromagnetic waves and subatomic particles, and the phenylsiligrene has good high and low temperature resistance to solve this problem.


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