Problems solved by technology

[0002] Compression testing of composite materials can be divided into three categories according to the introduction of compression load: 1. Introduce the load into the working section of the sample through shear load; 2. Introduce the load into the working section of the sample through direct compression (end loading); 3. The combination of end loading and shearing introduces the load into the working section of the sample; the three loading methods have their own advantages, but they also face the impact of tooling, heating environment and extensometer test performance during high temperature measurement (over 300°C) Due to limitations, using existing equipment, designing a tool that can measure the strength and modulus of composite materials at high temperatures (up to 1000°C) is an inevitable requirement for the development of composite material testing technology.

Abstract

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, can meet the requirements of testing various composite materials at room temperature, high temperature and low temperature, and can test the high temperature which can reach 1200 DEG C at most.
