Thermal Conductivity of Composite Materials Based on Microspheres and Fiberglass Binded by Styrene-Acrylic Emulsion
摘要
In the present work, the thermal conductivity of composite materials based on glass, ceramic, and polystyrene microspheres, as well as fiberglass, bonded with a styrene-acrylic emulsion has been reported. The measurements were performed using a commercial SKZ1061C instrument manufactured by SKZ Industrial based on the transient plane source (TPS) method at room temperature and atmospheric pressure. The reliability of the measurements was confirmed through validation of two reference samples of extruded polystyrene foam with well-known thermal conductivity. The measured thermal conductivity values range between (0.0581 and 0.0905) W/(m⋅K) with an uncertainty of 2.5%.
