The thermal conductivity and specific heat of seven different polyurethane foams and their melts were investigated using the Transient Plane Source. The thermal conductivity of the foams themselves ranged between 0.048 and 0.050 W/mK, while the thermal conductivity of the melt product was 0.186 to 0.200 W/mK, a difference of 300%. Melting had the opposite effect on the specific heat of the samples, which dropped 20% from a range of 2359 to 2996 J/kgK to 1958 ...
Understanding the pyrolysis model for medium density fibreboard (MDF) is important for infrastructure fire safety. The purpose of this study was to determine the thermophysical properties of charred and uncharred MDF. The thermal conductivity of these inhomogeneous fibreboards was measured using a Thermal Constants Analyser in conjunction with the transient plane source (TPS) technique. Results showed that the experimental results were in good agreement with literature values, and specifically, the ...
