Abstract
The recycling process of carbon fibres was investigated using thermal solvolysis of polymer composites in the medium of coal tar pitch in the 320–400 °С temperature range. The effect of thermal treatment therein on properties of carbon fibres isolated via the recycling was investigated. The paper presents research data by scanning electron microscopy and mechanical tests of isolated carbon fibres compared to the initial ones used for composite synthesis.
