Untersuchung der Sortierbarkeit kohlenstofffaserverstärkter Kunststoffe mittels induktiver Sensorik Investigation of the Sortability of Carbon Fiber-Reinforced Polymers Using Inductive Sensors

Carbon fiber-reinforced plastics (CFRP) are becoming increasingly important, particularly in the lightweight industry. To reintroduce high-quality carbon fibers (CF) into the recycling loop, they must be kept free from plastics containing foreign fibers for quality assurance purposes. Additionally, CFRP, with its contained CF, is often classified as a disruptive material in the treatment of mixed plastic waste. Effective sorting processes for CFRP are therefore of great importance for the entire recycling industry. This article deals with the investigation of the detection of CFRP with a thermoset matrix using inductive sensors. The systematic variation of different parameters of the input material shows that CFRP can be sorted under certain conditions.
