  • RECYCLING OF EPOXY RESINS AND POLYMER COMPOSITE MATERIALS ON THEIR BASES (review)
    In this work the most common methods of recycling of carbon and glass composite materials based on epoxy resins are discussed. Recycling of thermosetting polymers and materials on their bases are one of the most difficult questions in modern chemistry of composite materials. This class of materials cannot be melted by heat and re-molded, since there are many strong cross-linking bonds in them. Even more difficult is recycling of polymer composite materials, which are multi-phase materials, which contain fillers, fibers and cured polymer matrix.
    Keywords: recycling, thermosetting compositions, epoxy compositions, polymer composite materials.
