Study on mechanical and thermal characteristics based on a new type of metal matrix composite cabin

Abstract With the rapid development of aerospace technology, the aerodynamic heating problem faced by hypersonic vehicles makes it more and more demanding for the mechanical and thermal properties of cabin materials. The purpose of this study is to explore the performance of a new type of composite cabin under different temperature loads through mechanical and thermal simulation analysis. In the research, the simulation model is constructed based on the metal matrix composite instrument cabin, and the finite element analysis software is used to simulate the stress, strain, and load changes of the cabin during the temperature load of 200 °C, 500 °C and 800 °C, and compared with the traditional aluminum alloy 7075 material. The simulation results show that the new composite cabin has better mechanical and thermal performance under different temperature loads and shows good structural integrity and thermal stability while realizing a lightweight structure.
