Abstract : This study describes a thorough DSC study on the melting properties and thermal conductivity of hybrid polymer composite materials designed for ceiling boards. The hybrid polymer composite materials used in the study were made from a thermoplastic polymer base combined with organic and inorganic fillers in order to increase their thermal conductivity and mechanical stability. Melting temperature, crystallization behaviour, and crystallinity percentage were determined by using DSC because these properties are essential parameters for thermal conductivity. The results show that the use of hybrid filler plays a significant role in modifying the thermal performance of the polymer matrix, thus resulting in higher heat stability and changes in the melting behaviour of the composites. There is a remarkable change in the melting point and an increase in crystallinity due to increased interfacial interaction and better dispersion of fillers in the polymer matrix. This structural alteration helps improve thermal conductivity, rendering the composite a viable material for use in insulation and efficient ceilings. In addition, the complementary interaction between the organic and inorganic components contributes towards thermal stability and reduced heat transfer, hence ensuring thermal comfort indoors. Overall, it can be concluded from the results obtained that DSC is a powerful technique in understanding the thermal characteristics of hybrid composites, and the produced composite has excellent potential to replace traditional ceiling boards.
