High precision short fiber mechanical performance tester

The JSF08 high-precision short fiber mechanical property tester (SF Microteteer I) is an innovative achievement of the "948" project of the State Forestry Administration, which introduces the technology for testing the mechanical properties of bamboo and wood single fibers. The testing of short fiber mechanical properties has reached an advanced level.

There are widely used experimental instruments for measuring the strength of conventional fibers. However, for materials such as bamboo and wood fibers, which have small fineness, high strength, short length, and are brittle and easy to break, the preparation of samples in experiments is a major problem. At the same time, corresponding stretching devices are also required for this special material experiment. This stretching device was developed in this context, using a special precision chuck to clamp the sample, ensuring the fiber is straightened and does not slip during the stretching process. This instrument observes the surface morphology of fibers and captures the stretching process of fibers through a horizontal optical measurement system, and accurately positions bamboo fiber samples on the chuck through a vertical optical system.
