编织复合材料在高温热结构中的应用
Application of Braiding Composites in Design of High-Temperature Thermal Structures
摘要
Abstract
The 3D braiding composites is widely used in the field of aviation,aerospace and other high technology because of excellent properties.The resistance of 3D braiding composites to high-temperature is an important application.In this paper,the heat conduction characteristics of a revolving thin wall under high-temperature are obtained through the heat conduction analysis of a 2.5D braiding CFRP engine structure.Then,through the test under the ground state of oxygen enrichment,it is proved that the structure can be used under high-temperature of 950℃ for long time.The consistency of finite element analysis and test results verifies the calculation correctness and the rationality of compensation parameters selection in test.The study has a good guiding significance to the application of 3D braiding composites in engineering.关键词
