SOLVOLYSIS OF THE END-OF-LIFE COMPOSITE WASTES FOR GLASS AND CARBON FIBERS RECOVERY

Research output: Contribution to conference › Paper › peer-review

Abstract

Efficient recovery of carbon and glass fibers from large-size composite materials used in wind energy construction, end-of-life aircraft structures, etc. is a current technological problem. In order to identify the possibility of recovering these fibers, preliminary laboratory tests of batch low-pressure solvolysis process were carried out. The technical possibilities of controlling the solvolysis effectiveness and its time-course were verified by NMR analysis of the process solution. The structure of glass fibers and carbon fibers (SEM) recovered after batch solvolysis and their elemental chemical composition (EDS) were identified. Based on the results of preliminary research, basic recommendations regarding the technological concept of the process of fiber recovery from large-size composite materials are given.
