Abstract

Effective thermal conductivities of fillers and matrix reinforced composite models are analysed by using Finite Element (FE) simulation. The process parameters of different filler concentrations, filler piece arrangements and thermal conductivity ratio are analysed by Design of Experiment. In this study, simulation based on fully replicable five -factor, five-level central composite design. Regression models are developed to analyze the effects of process parameter. The responses are analyzing the direct and interactive effects. Three-dimensional cube matrix models have developed both Sphere and Cube filler arrangements. The top and bottom surfaces of the composite models temperatures are taken as a 40°C and 20°C remaining surfaces are perfectly insulated. The main aim of this research, an effective thermal conductivity found from simulation and compared with theoretical models. The simulation results are found closer with theoretical results.
