随着工业科技发展的需要,许多新材料(非金属材料及复合材料)不断地被研究和开发出来并获得应用,其中不少材料需要工作在恶劣环境下(例如高温或低温),对这些材料进行力学性能测量无论对材料研究、产品设计和生产都是十分必要的.如用于航空发动机叶片的材料要工作在数百度的高温 With the development of industrial science and technology, many new materials (non-metallic materials and composites) are constantly being researched and developed and applied, many of which need to work in harsh environments (such as high or low temperature), these materials For mechanical properties measurement of material research, product design and production are very necessary.As used in aviation engine blades to work in the hundreds of high temperature
