In addition to high stress and inertial force, aerospace materials also experience shock loads and alternating loads caused by factors such as takeoff and landing, engine vibration, high-speed rotation of rotating parts, maneuvering flight, and sudden winds. Engine gas and solar radiation cause the aircraft to be in a high temperature environment. As the flight speed increases, the aerodynamic heating effect is prominent, resulting in a "thermal barrier". In addition, it has to withstand alternating temperatures. When the stratosphere flies at subsonic speeds, the surface temperature will drop to about -50 ° C, the severe winter ambient temperature in the polar circle will be lower than -40 ° C, and metal components or rubber tires are prone to Embrittlement phenomenon. Gasoline, kerosene and other fuels, as well as various lubricants and hydraulic oils, mostly have a corrosive effect on metal materials and a swelling effect on non-metallic materials, while mold generated by solar radiation, wind and rain erosion, and long-term storage in underground humid environments will accelerate the aging process of polymer materials.

Facerom was established in 2014, and the company is located in Hefei, one of the four major scientific and educational cities in China.
