Experimental and Computational Analysis of Thermal Characteristics of Polymer Resin Reinforced with Rice Husk and Aluminium Nitride Filler Composites

This research paper investigates the possibilities in enhancing the typical thermal conduction capability of particulates-filled hybrid polymer composites. Different samples of rice husk (RH) and aluminium nitride (AlN)-filled polymer composites are fabricated using simple hand layup method, while the substance of fillers (AlN and RH) in the composite is varied in the range of 0–20 wt% with various combinations. Composite samples with different ratios like 1:1, 1:3, and 3:1 wt% are used in our present study. The thermal conductivity of these samples is determined by using the hot disc method as per ASTM standards. Thermal mechanical analysis provides valuable information on the coefficient of thermal expansion and glass transition temperature ( T g ) on the composite material having different ratios by using a constant force that varies with temperature. Scanning electron microscope was used to analyse the molecular structure and exterior morphology of the two different fillers, as well as their interaction with the matrix. The effectual heat conductivity of hybrid polymer resin composites is predicted using a FEM simulation method, and its values are validated with experimental data.
