FIELD: chemistry.
SUBSTANCE: invention relates to recycling polymer composite materials (PCM) wastes. Method of recycling filler from wastes of polymer composite materials containing thermosetting polymers based on epoxy resins with filler in form of glass fibre and carbon fibres, is carried out by thermal treatment at temperature of 340–380 °C in a solvent with release of filler and extraction of phenol products, wherein solvent used is oil pitch.
EFFECT: technical result consists in ensuring environmental safety of PCM recycling and return of valuable reinforcing fibres.
