Effective thermal conductivity of epoxy matrix composites filled with granite dust

Singh, Anunay Kumar (2014) Effective thermal conductivity of epoxy matrix composites filled with granite dust. BTech thesis.



Particulate filled polymeric composites with upgraded thermo-physical properties are very popular in electronic industry. This project exhibits a numerical, analytical and experimental examination on the thermal conductivity upgrade of granite dust filled polymer composites. Watched heat flow meter test technique is utilized to measure the thermal conductivity of granite powder filled epoxy composites utilizing an instrument Unithermtm Model 2022 as per ASTM-E1530. In the numerical study, the finite element method (ANSYS) is utilized to compute the conductivity of the composites. Three-dimensional solid shape-in-3d square and sphere- in-block cross section cluster models will be utilized to recreate the microstructure of composite materials for different filler size and concentration. The effect indicates that the effective thermal conductivity increments with augmentation in volume fraction of filler material i.e. granite dust. The experimental value and numerical values of effective thermal conductivity are compared with models values. It is discovered that the values got for different composite models utilizing Finite Element Method (FEM) are in sensible concurrence with the experimental values.
