Abstract

The invention discloses a device for testing zero distortion of a carbon fiber member, which comprises a high-low temperature control cabinet [1], a high-low temperature testing box [2], a measurement system control box [3], a temperature sensor [4], an MTI2000 optical fiber displacement sensor [5], a computer control and analysis system [6] and a carbon fiber member [7]. The device solves the problem of poor precision of detecting a thermal expansion coefficient of the traditional carbon fiber member. By adopting the device for testing the zero distortion of the carbon fiber member, the detection problem of zero distortion performance of the carbon fiber material member in a working environment with larger temperature difference variations can be solved. The device for testing the zero distortion of the carbon fiber member has the advantages of simpleness and convenience for operation, high detection precision and low equipment cost.

Description

technical field [0001] The invention relates to a deformation detection device, in particular to a test device for detecting the zero deformation state of a carbon fiber component with a large temperature change under an operating temperature field. Background technique [0002] Satellites operating in geosynchronous orbit, because there is no protection of the atmosphere, the ambient temperature changes greatly. The temperature on the sunny side can be as high as hundreds of degrees, but the temperature on the back side is tens of degrees Celsius below zero. Therefore, satellites operating in this environment will cause dimensional changes in the satellite structure due to thermal expansion of materials. However, considering the technical requirements of certain components and instruments of the satellite, it is hoped that the stability of the satellite structure will be good. Therefore, such components will be made of zero-deformation carbon fiber materials. However, the ...
