Composite material high-temperature compression tool and tensile testing machine

The invention discloses a composite material high-temperature compression tool and a tensile testing machine. The composite material high-temperature compression tool comprises a base mechanism, a clamping mechanism, a tool mechanism, a connecting mechanism, a compression mechanism and a temperature control mechanism, the clamping mechanism is fixedly installed at one side of the base mechanism, the base mechanism and the clamping mechanism jointly form a tool mechanism, the compression mechanism is arranged in the connecting mechanism, and the temperature control mechanism is fixedly installed in the periphery of the connecting mechanism. According to the invention, by arranging a mounting groove, a common extensometer can be mounted in the mounting groove to measure a high-temperature material sample, so that the common extensometer is prevented from being damaged by the high-temperature material sample; and a replaceable base plate is arranged on the base, so that the tool is wider in application range, ca
