Recycling, reclamation and re-manufacturing of carbon fibres

The recycling of carbon fibre reinforced polymers (CFRPs) is much needed due to the environmental challenges posed by traditional landfilling. Although, various recycling techniques have been used for the recovery of carbon fibres from waste materials, the recycled fibres have limited applications due to partial deterioration of mechanical properties and shortening of fibre lengths. This review article aims to shed light on the advancement in the carbon fibre recycling techniques from used composite materials. Further, the disadvantages of mechanical and thermal recycling approaches over chemical recycling such as production of low quality fibres, low tensile strength, char deposition, etc. have been brought out concisely.
