CFM-PYR-H-1

Carbon short fibres which are gained by pyrolysis (at > 1200 °C) of production remnants (prepregs) and made by milling. In the case of thermoplastics a particular good electrical conductivity is achieved by adding carbon short fibres because of their high carbon content (> 95 %) and due to additional carbonizing. Average fibre length can be influenced by sieve perforation. Longer fibres allow an electrical conductivity of the plastics, even with additives below 4 %. A 1 mm -perforated sieve is usual and results in a mean fibre length of approx. 200 µm and a good free-flowing behaviour. A very constant quality is ensured due to homogeneous source materials.
