In this paper, the suitable method for measuring the performance data of composite materials is first discussed. The characteristics of this material are analyzed from the perspective of structural design. The damage modes and the fracture morphology of the materials are introduced. The fracture characteristics of the materials and the characteristics of the test pieces Then put forward several physical models that can be used for reference in thermal stress calculation. Based on the brief introduction of high temperature biaxial loading device, the strength failure criterion and fracture failure of the material are discussed. The materials and components are introduced with emphasis Several new detection methods; Finally, the introduction of several theoretical treatment.
