Epoxy composites containing CFRP powder wastes

The increasing utilisation of carbon materials increases the waste generation. Therefore, it is necessary to analyse recycling alternatives. In this research, carbon powder wastes obtained from the cutting process of laminate composites have been incorporated into epoxy matrix phase in order to improve the mechanical characteristics. Physical and mechanical properties, hardness, abrasion, erosion and thermal behaviour have been analysed. Results show that carbon powder wastes incorporated to new epoxy matrix phases act basically as reinforcement. This allows for the recycling of the residues as well as improves some properties of the composites. (C) 2013 Elsevier Ltd. All rights reserved.
