|Abstract:||Thermophysical properties such as, effective thermal conductivity (λc) and effective thermal diffusivity (c) of untreated reinforced phenol formaldehyde with different weight per centages of oil-palm- fibre (x) are measured simultaneously using the transient plane source (TPS) technique between 80 to 120°C. The composites investigated contain 20, 30 and 50 weight percentage of oil-palm-fibre. The experimental results at different weighted composites show that there is variation in λc and c in this temperature range. However, a maximum value of λc and c is observed at 100°C, which lies in the vicinity of glass transition temperature (Tg) of these composites. Efforts are also made to predict the weight percentage of oil-palm-fibre (OPF) and temperature dependence of λc and c through the development of an empirical model. Theoretical predicted values of λc and c for these composites are in agreement with experimental results over the entire range of temperature for investigations|
