Russia developed high temperature resistant superhard composites

Researchers at Moscow University have developed a new type of polymer composite material that has good heat resistance compared to similar materials, and has good market applicability in production technology and cost. At present, the series of materials synthesized by Moscow University are being tested at the Baranov Central Aero Engine Manufacturing Institute, the Kato Tupolev National Research Technology University and other Russian aviation industry institutions.

Before the Moscow University developed this series of heat-resistant polymer composite materials, the scientific community generally believed that the maximum temperature that the composite material can withstand is 250 degrees Celsius. However, the composite materials developed by Moscow University have been tested to withstand temperatures of 450 degrees Celsius, which exceeds the aerospace aluminum and titanium materials.

The synthesis of the composite is based on two relatively simple polymers: unsaturated alkyne and benzene and nitrogen compounds. These materials are generally used to make orange pigments, but the combination of these materials can form high-strength, high-temperature resistant composites. It is also because the raw materials are easily available, making the cost of the new materials much lower than similar high hardness. Composite material.
