Micro-nano single fiber mechanical testing is used to measure the mechanical properties of micro-nano single fibers. Equipped with a proprietary sample preparation platform, it solves the problem of difficult sample preparation for micro-nano single fibers. So, what is its principle? What are its equipment specifications? Let me introduce them to you below.
I. Principles of Micro-Nano Single Fiber Mechanical Testing
1. Receive the micro-nanofibers through a special sample stage offline, and place the sample stage with the micro-nanofibers on the equipment.
2. By combining low and high-power digital microscopes and using a specially designed cutting system, excess micro-nano single fibers are cut away under the microscope, leaving only a single micro-nano single fiber on the sample stage, thereby completing the preparation of the single micro-nano fiber sample.
II. Equipment Specifications for Mechanical Testing of Micro-nano Single Fibers
1. Sample preparation platform for micro-nano single fibers: This platform is specifically designed for sample preparation of special fibers such as micro-nano single fibers or conventional fibers.
2. The force resolution reaches 0.1mg (1μN), with a maximum range of 60g (60cN), suitable for testing the mechanical properties of various fibers.
3. Tensile testing system for elongation performance testing of micro-nano single fibers, with a range of 100mm, a repeatable positioning accuracy of ±10μm, and an Omron photoelectric protection switch to ensure the tensile system is not damaged. The tensile speed range is 0.1mm/min to 250mm/min, with continuously adjustable speed.
4. The entire instrument adopts a horizontal structure design, making it convenient for sample loading.
5. The enclosed chamber system for placing samples ensures that the testing process is not affected by external interference, protecting the test samples.
6. The testing fixture system, specifically designed for holding the offline sample preparation platform.
7. The spacing of the fixture system is continuously adjustable (can be positioned at 5mm, 10mm, 15mm, etc.), with a minimum of 2mm.
8. The illumination system for observing micro-nano single fibers in the darkroom, which can be used to observe the spatial position and morphology of micro-nano single fibers.
9. The anti-vibration design of the entire machine prevents instrument vibrations caused by the stretching process or the external environment from affecting the test data.
10. The PC software can control various functions of the device, record and store experimental data, and plot stress-strain curves; it can also set various test modes, such as tensile mode, cyclic tensile mode, constant elongation mode, etc.
The above is the analysis of the "principles and equipment specifications for micro-nano single fiber mechanical testing". Please feel free to contact us if you have any questions.
