Manufacturing method of clamp for testing high-temperature mechanical properties of material
The invention discloses a manufacturing method of a clamp for testing the high-temperature mechanical property of a material, and belongs to the technical field of design and manufacturing of clamps for performance testing. The high-temperature mechanical property test fixture for the C/C composite material containing the deep SiC coating is prepared by adopting a mixed process of an electric coupling chemical vapor infiltration process (E-CVI), a resin impregnation and cracking process (PIC) and a chemical vapor deposition process (CVD) through structural design. The prepared test fixture can be used in air, inert atmosphere, vacuum and other environments at the temperature of 1000-1700 DEG C, and can be used in inert atmosphere or vacuum at the temperature of 1800 DEG C or above. And meanwhile, the clamp has relatively long service life and relatively low test cost.
本发明公开了一种材料高温力学性能测试用夹具制造方法，属于性能测试用夹具设计及制造技术领域。通过结构设计并采用电耦合化学气相渗工艺(E‑CVI)、树脂浸渍裂解工艺(PIC)与化学气相沉积工艺(CVD)混合工艺制备出含有深度SiC涂层的C/C复合材料高温力学性能测试夹具。所制备测试夹具可实现温度1000～1700℃空气、惰性气氛和真空等环境使用，以及1800℃以上惰性气氛或真空下使用。同时，夹具具有较高的使用寿命和较低测试成本。
