Abstract

The invention relates to a tension experiment measuring and detecting device, in particular to an in-situ nano tension experiment measuring and detecting device. The invention solves the problem in the prior art that measurement of mechanical properties and detection of micro-morphology are two independent and separate processes. An output shaft of a stepper motor (1) of the device is fixedly connected with a coupler (2); a guide rail (7) is fixed on a stander soleplate (4); a left frame set (42) and a right frame set (43) are arranged on the guide rail (7); both ends of a left and right rotary screw (8) are respectively connected with the coupler (2) and a bearing support (21); a left end face and a right end face of a force sensor (18) are respectively and fixedly connected with a right clamp connecting block (14) and a force sensor holder (19); a reading device (44) is arranged on the stander soleplate (4); and a tension measuring device (41) is fixed on a worktable (46) of the detection device. The in-situ nano tension experiment measuring and detecting device promotes further development of the research area of dynamic observation required on the micro-morphology variation of a sample under the state of stress, and has important theoretical significance and good application prospect on measurement of the mechanical properties and detection of the micro-morphology of composite functional nanophase materials.

Description

technical field [0001] The invention relates to a tensile test measuring and detecting device. Background technique [0002] Usually, the mechanical performance of nanocomposite functional materials is tested by tensile experiments, and the mechanical performance parameters such as fracture characteristics and elastic modulus of materials are analyzed by obtaining real-time stress-strain curves. The microscopic morphology of nanocomposite functional materials has a great influence on its mechanical properties. At present, scanning electron microscopy (SEM) and atomic force microscopy (AFM) are mainly used to characterize the microstructure of nanocomposite functional materials. People analyze the data obtained from the two experimental methods of tensile experiment and microstructure detection, and then optimize the production process of nano functional materials. In this process, the measurement of mechanical properties and the detection of microscopic morphology are two i...
