What materials are used for rockets?

The universal carrying casing is made of cerametal, aluminum alloy, or engineering plastic, but it’s definitely not one of the common types you see everyday. As for the formula, it should be a secret. These materials are chosen for their light weight, resistance to seismic forces and fatigue, low cost, and good heat resistance. As for military applications, materials such as those used for stealth and interference resistance are more complex to consider.

Ceramics and aluminum alloys should be fine; engineering plastics probably won’t work, as how can they withstand high temperatures?

How high can the temperature of a rocket reach?

Ceramics: Key Materials for Modern Rockets and Spacecraft. Ceramics are created by mixing ceramic powder with metal powder and then sintering them at high temperatures. These materials are both hard and tough, have a low density, and can withstand high temperatures. As a result, they are increasingly used in launch vehicles, intercontinental missiles, space shuttles, and spacecraft. The launch tubes for America’s MX missiles were originally made of special steel and weighed 40 tons; however, after using special ceramic-metal composite materials, their weight was reduced to about one-fifth of the original value. Many countries now take advantage of the high-temperature resistance and impact resistance of oxide ceramics by using them in armor systems. Ceramic composite armor offers advantages that metal armor cannot match—it can not only resist attacks from conventional ammunition but also withstand attacks from neutron bombs and anti-tank missiles. Germany’s “Leopard-87” tank uses a composite armor made up of ceramics, rubber, and special resins, which enables it to withstand the shock waves and thermal radiation from nuclear weapons. This is currently the most advanced composite armor in the world. When space shuttles and spacecraft pass through the atmosphere, the temperature on certain parts of their surfaces can exceed 2,000 degrees Celsius. To ensure that the instruments and equipment inside function properly and to protect the lives of the crew, these vehicles are equipped with numerous high-temperature resistant ceramic thermal protection panels. Such panels can be reused more than 100 times.
