◆Mechanical property testing: Although the scanning electron microscope itself does not directly test mechanical properties, it can indirectly evaluate mechanical properties, such as strength, toughness, etc., by observing the micro morphology and structural characteristics of fibers.

◆Functional evaluation: For fibers with special functions, such as flame retardant fibers, antibacterial fibers, etc., the scanning electron microscope can be used to observe the distribution and morphology of their functional components, so as to evaluate their functional properties.

◆Observation of modification effect: The scanning electron microscope can be used to observe the microscopic morphologic changes of fibers before and after modification, so as to reveal the modification effect and mechanism. For example, it can be used to observe the surface roughness and pore structure of the modified fiber.

◆Modification process optimization: By comparing the micro morphology and performance changes of fibers under different modification processes, the modification process parameters can be optimized to improve the modification effect.

◆Special fiber development: The scanning electron microscope plays an important role in the development of special fibers such as carbon fibers, glass fibers, etc. By observing the micro morphology and structural characteristics of these fibers, it can guide the improvement of their production process and performance.

◆Composite materials studies: In the field of composite materials, the scanning electron microscope can be used to observe the interface bonding between the fiber and the substrate and evaluate the performance of the composite materials. It is of great significance for the development of high-performance composite materials.
