Recycling of glass fibers sheets from thermoset reinforced plastic using thermolysis method

Abstract

Abstract This article presents research data on the process of recycling fiberglass reinforcing fillers from polymer composite materials. The analysis of the thermal stability of the polymer matrix is carried out. In this work, the thermolysis of fiberglass reinforced plastic based on E-glass and the epoxy vinyl ester binder was carried out at 400 °C. The influence of thermolysis time on the strength of composite materials based on regenerated reinforcing glass filler was studied. The PCM sample made of the filler obtained by 30-minute treatment at 400 °C and cooled in water withstands the bending load by 1.6 % lower than that of the primary material.
