Abstract: Guarded heat flow meter test method is used to measure the thermal conductivity of pine wood dust filled epoxy composites using an instrument UnithermTM Model 2022 in accordance with ASTM-E1530. In the numerical study, the finite-element package ANSYS is used to calculate the conductivity of the composites. Three-dimensional spheres-in-cube lattice array models are used to simulate the microstructure of composite materials for various filler concentrations ranging from about 6 to 36 vol%. This study reveals that the incorporation of pine wood dust results in reduction of conductivity of epoxy resin and thereby improves its thermal insulation capability. With addition of 6.5 vol% of filler, the thermal conductivity of epoxy is found to decrease by about 19.8% and with about 36 vol% of filler addition, a 57.3% reduction in thermal conductivity of neat epoxy is achieved. The experimentally measured conductivity values are compared with the numerically calculated ones and also with the alr...
