Abstract
The review of foreign studies devoted to the utilization of polymeric composite materials (PCM) by the solvolysis method is presented. It has been established on the basis of this that two groups of technologies predominate: directed to fiber extraction by destruction of the organic matrix and based on partial destruction of individual bonds while preserving valuable matrix components. The results of experimental studies on the selection of reagents for the recovery of carbon fiber from phenol formaldehyde PCM are presented. The characteristics of the change in the properties of the secondary fiber on the basis of a visual assessment are given, showing the appearance of roughness and irregularities in the fiber swirl and a significant decrease in their thickness. The results of research on fine-dispersed reinforcement of concrete with secondary carbon fiber, which showed an increase in flexural strength by 3–8 %, are described. The problem of dispersion of secondary carbon fiber during its introduction into concrete is considered.
