| Abstract | ||
| The effects of reinforcement of Carbon Nano Tubes ( CNTs ) on thermal properties of epoxy resin based composites was studied. Epoxy resin was reinforced with CNTs type multi-walls (MWCNTs ) to prepare nanocomposites with different volume fractions. Hand lay - up technique was used to prepare the nanocomposites. Thermal tests included thermal conductivity measurement by using Lees disc and erosion rate test by using oxy-acetylene flame technique. Thermal conductivity is calculated theoretically via simulation operation by using Nielsen model. Simulation programs of heat transfer in three dimensions for erosion test of epoxy nanocomposites specimens were carried out using finite difference method. Thermal conductivity results show that the values increase progressively by increasing of volume fraction of (MWCNTs ). Erosion rate behaves inversely, where it drops at high volume fractions of (MWCNTs ) because of there help to transfer heat flow more than epoxy was alone. Ablation test results of experimental work and theoretical simulation were compared to understand the nature of adhesion mechanism between components of nanocomposite material. This comparison included the variation of the above measured and calculated properties in different volume fractions of the (MWCNTs ). | ||
