Abstract
In the present research work, the thermal conductivity of unfilled and marble dust filled needle punched nonwoven jute-epoxy composite is investigated. The hybrid composites are prepared using vacuum assistant resin transfer molding (VARTM) process with varying the wt.% of marble dust (filler) from 0 to 24 wt%. The hot disk transient plane source (TPS) thermal constant analyzer is used to measure experimental thermal conductivity. The analytical thermal conductivity is estimated using different theoretical models and Finite element simulation package ANSYS workbench. Three-dimensional model is used to simulate the thermal conductivity of fabricated composite for various filler concentrations. The Temperature and heat flow are considered as the input parameters, while heat flux is output for the finite element simulation. The experimental results indicate that the thermal conductivity increase with increase the filler wt.% in the composite. The result obtained from the theoretical models and ANSYS are found to be in good agreement with the experimental results.
