Plastic reinforcement chopped carbon fiber
Chopped carbon fiber
Short-cut carbon fibers have good fluidity, and the shorter the length, the better the fluidity. By mixing short-cut carbon fibers with resin and granulating, then using injection molding to make various products, large-scale production can be achieved.
In the composite material industry, according to the range of matrix resin usage, it is required that the sizing agent must be compatible with the final matrix during the manufacturing process. In recent years, the progress in slurry chemical properties has led the industry to shift from solvent-based slurries to water-based slurries, making the sizing process cleaner and more environmentally friendly.
There are four common types of short-cut carbon fibers: sheet-shaped, cylindrical, irregular, and unsized. The feeding capacity of twin-screw equipment is: cylindrical > sheet-shaped > irregular > unsized (unsized short-cut fibers are not recommended for twin-screw equipment use).

Among them, cylindrical short-cut carbon fibers have higher requirements for raw materials and processing equipment, but their performance is also better.
