ABSTRACT
Development of this two-year-long research project has allowed us to show that both chemical techniques, such as the digestion of resin with nitric acid, and heat treatment techniques, such as pyrolysis in a controlled environment, can be used to recycle epoxy-based thermostable composite materials, obtaining a carbon fiber that can be used as a short reinforcement for new materials. The fact that we can provide an outlet for the carbon fiber obtained as the product of a recycling process justifies its use, and it has been shown that it can be combined with thermoplastic materials such as polypropylene (PP) or polyamide (PA) in percentages of up to 30%, giving the composite material generated excellent mechanical properties at a price similar to that of materials currently used. It also closes the complete recycling circle by using the recycled material in a new application. A last resort would be to use these materials for energy generation by taking advantage of the possibilities of using them as fuel.
