Mechanical properties are the main indicators for evaluating material quality and the primary basis for design and calculation. Different application fields have different requirements for the mechanical properties of materials, and the principles also vary. So, what is the principle of micro-nano single fiber mechanical testing? What should be noted during testing? Let me introduce it 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 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 fiber on the sample stage, thereby completing the preparation of single micro-nano fiber samples.
II. Precautions for Mechanical Testing of Micro-nano Single Fibers
1. The minimum spacing of the sample stage reaches 0.1mm,
2. The maximum magnification of the high and low magnification digital microscope system reaches 8 pixels/μm
3. The parallel light source serves as background light, allowing for clear observation of the sample
4. The dual-sided cutter system enables precise movement in three dimensions
5. The fixture system for securing the sample stage enables precise movement in three dimensions
6. The enclosed chamber design eliminates the influence of external stray light
