- Description
-
Short-cut carbon fiber is made of short-cut PAN-based carbon fiber filaments, and its basic properties mainly depend on the properties of its raw material-carbon fiber filaments. Being composed of equal length fluff, short fiber offers uniform dispersion, versatility of mixing methods and an easy processing step compared to longer filaments.
The role of short-cut carbon fiber in friction sealing material products
a. Enhance the thermal stability of products
b. Reduce deformation, improve anti-slip and wear resistance
c. Improve the crack resistance of products
d. Improve the dispersion of other raw materials in the product
e. Improve the tensile strength and toughness of the products, and improve the impact resistance of the products.

Special fibers have different special properties, such as strong corrosion resistance, low wear, high temperature resistance, radiation resistance, flame resistance, high voltage resistance, high strength and high modulus, high elasticity, reverse osmosis, filtration, adsorption, ion exchange, light conduction, conductivity, and various medical functions.
Most specialty fibers are made by wet spinning. Some special fiber preparation processes are more difficult, such as spinning linear or low molecular weight fibers using traditional spinning techniques, and then undergoing cyclization, cross-linking, metal chelation, high-temperature heat treatment, surface physicochemical treatment or plasma treatment to produce finished fibers; In addition, new spinning processes such as lotion spinning, reactive spinning, liquid crystal spinning, dry jet wet spinning, phase separation spinning, high voltage electrostatic spinning, high-speed airflow melting jet and special composite spinning technologies are needed; Some also utilize existing synthetic fibers to obtain various ion exchange groups through functional group reactions or convert them into special fibers.
