Microwave heating as a means for carbon fibre recovery from polymer composites: a technical feasibility study
Carbon fibre composites with an epoxy resin matrix were subjected to microwave-heating experiments in order to volatilise the polymer content and to produce clean fibres for potential reuse in high-grade applications. The composites were processed at 3 kW for 8 s in a multimode microwave applicator. The recovered fibres were characterised by tensile tests and electron microscopy. The results compare favourably with virgin fibre properties. (C) 2004 Elsevier Ltd. All rights reserved.
