High-temperature biaxial testing machines in aerospace.

High-temperature biaxial testing machines play an important role in the aerospace sector, being able to simulate complex mechanical and thermal environments similar to those encountered by airplanes in all phases of flight. This paper begins with an overview of the principles and development of high-temperature biaxial testing machines and then discusses their test methods as well as the testing machine's measurement system. In addition, this paper emphasizes the importance of high-temperature biaxial testing in evaluating critical aerospace components, thereby underscoring its indispensable significance in improving the reliability and safety of aircraft. Finally, this paper identifies ongoing challenges and potential avenues for future research, including expanding material adaptability, improving the accuracy of the resulting simulations, and increasing testing capabilities under more demanding conditions.
