AI Technical Summary
Technical Problem
During high-temperature tensile testing of ceramic matrix composites, the debris generated by material fracture can cause injury to test personnel, damage equipment, and pollute the environment, affecting the accuracy and reliability of the test.
Method used
A tensile testing machine including a liftable lifting plate and a protective component was designed. The protective component consists of a movable cover and a cleaning component. The movable cover seals off debris during the test and automatically cleans up the debris after the test.
Benefits of technology
It effectively blocks debris from splashing, preventing personal injury and equipment damage, keeping the testing environment clean, and improving the reliability and repeatability of test results.

Abstract
The invention relates to the technical field of material tensile test detection, and discloses a ceramic matrix composite material high-temperature tensile creep test device, which comprises a tensile testing machine, a liftable lifting plate is arranged on the tensile testing machine, a first clamp is mounted on the tensile testing machine, and the first clamp is mounted on the tensile testing machine through a vertical rod; a first clamp is mounted on the lifting plate, a second clamp is mounted on the lifting plate through a vertical rod, the first clamp is arranged right opposite to the second clamp, a fixing plate is fixed on the tensile testing machine body, and the fixing plate is arranged in the height direction of the tensile testing machine. According to the invention, through a closed cover body structure formed by splicing the double moving covers, the ceramic matrix composite material in the testing process is completely wrapped, so that high-speed chippings generated when the material is broken are effectively prevented from splashing, and mechanical injury and high-temperature scalding risks to operators are avoided.
