Abstract

Carbon fibre reinforced plastic (CFRP) is being used in increasing quantities particularly in the transport industry to reduce carbon emissions through weight reduction and in the energy industries for renewable technologies, such as wind turbines. As a high value and energy intensive material to manufacture a good case can be made for recovering and reusing carbon fibre from waste material. A number of companies in Europe and the USA are now in the early stages of commercial operation, but the focus is upon the recycling of clean, uncontaminated scrap from manufacturing processes and it is recognised that CFRP that is mixed with other materials eg. sandwich panels, metal inserts, painted surfaces and composites made from toughened polymers are more difficult to recycle effectively with existing commercial processes. The fluidised bed process developed at the University of Nottingham for recovering carbon fibre from waste composite material has the potential to process mixed and contaminated CFRP waste. The oxidising conditions allow full removal of any organic materials and the fluidised bed effectively separates the carbon fibres from other incombustible materials, such as metals. The process has now been developed to a scale representative of commercial operation and a waste CFRP comprising intermediate modulus carbon fibre and toughened epoxy resin has been processed successfully and good quality recycled fibres recovered. This paper will present the results and discuss the quality of the carbon fibre recovered from the process. A discussion of some of the key requirements to build a viable fluidised bed plant will also be presented.
