The invention relates to a high-temperature compression test clamp. The clamp comprises an upper compression body and a lower compression body, wherein the upper compression body and the lower compression body are U-shaped components; the U-shaped opening ends of the upper and lower compression bodies are arranged in opposite directions, and are in crossed butt joint to form a compression cavity for accommodating a sample; and the sample is fixed in the compression cavity along the compressing direction. According to the high-temperature compression test clamp, the upper compression body and the lower compression body which are in crossed butt joint are adopted, and the tensile force of the upper and lower compression bodies is transformed into pressure for the sample, so that a compression performance test is carried out by a tensile mode. The high-temperature compression test clamp is simple in operation, does not require strict alignment operation, and has the characteristics of simple structure, convenience in use and relatively high measurement accuracy.
Description
technical field [0001] The invention relates to a test device for a compression test, in particular to a high-temperature compression test jig used for a compression test under high-temperature conditions. Background technique [0002] At present, the rapid development of high-tech industries such as aerospace has brought higher requirements for materials, and high-temperature performance testing has become a research hotspot. High temperature tensile test is relatively mature, but the development of high temperature compression test is not perfect enough. On the one hand, it is due to the complexity of the material compression test itself, and on the other hand, the fixture used for the compression test has always been to be improved. [0003] However, the sensors used in most of the existing tensile testing machines are unidirectional, which makes it impossible to directly use conventional compression fixtures for high and low temperature compression experiments. A high-...
