Such materials are required in industries where thermal management is desirable but electrical conductivity is not required, such as substrates for electronic components and solar panels. In this study, the multi-scale modeling of epoxy (bisphenol-A) reinforced alumina composite has been performed using BIOVIA Materials Studio and Abaqus. Modeling has been done for varying volume fraction (Vf) of alumina. The properties predicted are the thermal conductivity and Young’s modulus. Heat transfer analysis has been done using Abaqus/Explicit. It was found that the thermal conductivity first increased till Vf  = 20% and then decreased. When the concentration of alumina was increased further after Vf  = 20%, the orientation of alumina particles changed from being in-plane to random, resulting in a fall in the values of thermal conductivity. In the silicon/insulator plate system, there was found to be an accumulation of heat resulting in a decrease in temperature on the bottom surface of the insulator plate. Thus, more time was taken for the heat to conduct through this system. Whereas, when the heat was transferred through the system of silicon/composite plate, no accumulation of heat in the system was observed. %U https://aml.iaamonline.org/article_14031_745ce62644c3aedc85db2adbfd2fa5cd.pdf
