Eirich granulating of short carbon fibers

Eirich presents a granulation technology for conditioning short carbon fibers from production leftovers, to use them for reinforcement of plastics. The advantage over new carbon fibers is the significantly lower price.

In order to process the hardened ‘prepreg’ leftovers, they are cut or ground, e.g. to fiber lengths below 500 µm. Naturally, a certain amount of dust is produced in the process. The fibers tend to form clumps, and the demixing that occurs makes accurate feeding very difficult. This is why it is advantageous to improve processability of the ground fibers through granulation. The Eirich mixer has a rotor which can run at a tool speed of up to 30 m/s. This makes it possible to generate high shear forces and distribute liquids quickly and uniformly. The process parameters are to be determined in the Eirich test center and are then easily transferable to larger production machines.
