RESUMO:

Thermoplastic Polymeric Materials have high potential for large scale production at low cost. The use in solar collectors is currently restricted the applications of low temperatures, generally for the heating of swimming pools. The greatest limitation in relation to the metallic collectors is the due to the low thermal efficiency in temperatures higher than 40°C. The present work consists on the development of a polymer matrix composite with the application of dispersed carbon-based additives to increase the thermal conductivity (usually between 0.1 and 0.4W/m.K) and to values higher than 1W/m.K , thereby improving the thermal performance of polymeric solar collectors. Cylindrical test bodies will be produced in Acrylonitrile Butadiene Styrene (ABS) for the measurement of thermal conductivity. Initially the pellets of the polymers (virgin and recycled) will be extruded for the dispersion of the additives and then thermoformed in cylindrical bodies for the measurement of the thermal conductivity. The measured data will be used in numerical simulation software to predict the performance of solar collectors manufactured with the obtained materials.
