Abstract:
The development of industries that actively use polymer composite materials leads to the accumulation of a large amount of waste in terms of spent products and their elements, resulting in serious environmental problems. This paper presents the method and results of an experimental study aimed at solving the urgent problem of recycling polymer composite materials. Recycling is implemented via pyrolysis induced by thermal radiation effect. The URAN-1 setup is used as a source of thermal radiation to generate a directed radiant heat flux of a given power on the sample under study. The experiments are carried using the polymer composite materials based on organoplastic and polycarbonate. The effect of heat flux density and exposure time on ablation rate and energy is revealed and analyzed. For the organoplastic material, the ablation energy decreases from $5.8$ to $3.6$ kJ/g with an increase in the heat flux density in the range $(42 \div 105)$ W/cm$^2$, and for the polycarbonate material, the ablation energy remains constant. The obtained results can be used to optimize the pyrolysis of polymer composite materials when solving the issues of recycling and reducing the volume of environmental pollution.
