“…Most commonly, the modeling is based on an equivalent circuit of the thermal resistance, which includes those of the TIM and of the interface between the TIM and each of the two proximate surfaces. 2,[18][19][20][21] The thermal resistance of this interface has been modeled by consideration of the degree of filling of the valleys in the surface topography. 2,18,19 However, the complexity of the combination of geometric, thermal, mechanical, and material factors calls for finite element modeling, which is the method used in this work.…”

The use of simple analytical equations in place of finite element modeling was found in this work to be inadequate, so no analytical model is presented here.…”

Finite element modeling is conducted to understand the factors that govern the performance of thermal interface pastes of controlled thickness between copper surfaces of controlled roughness. Carbon black paste is lower in thickness than metal particle paste, so it shows better performance. The performance of both pastes is more influenced by the paste-copper interfacial conductance than by the paste thermal conductivity. The effects of pressure, paste thickness, and copper surface roughness on performance are mainly due to the change in fractional filling of the valleys in the copper surface topography. Reasonable agreement is found between modeling and experimental results.

Graphene nanoplatelets (GNPs) have attracted considerable attention in the field of thermal management materials due to their unique structure and exceptional thermal conductive properties. In this work, we demonstrate a significant synergistic effect of GNPs, alumina (Al 2 O 3 ), and magnesia (MgO) in improving the thermal conductivity of polycarbonate/acrylonitrile-butadienestyrene polymer alloy (PC/ABS) composites. The thermal conductivity of the composites prepared through partial replacement of Al 2 O 3 and MgO with GNPs could increase dramatically compared with that without GNPs. The maximum thermal conductivity of the composite is 3.11 W mK 21 at total mass fraction of 70% with 0.5 wt% GNPs loading. It increases 60% compared with that without GNPs (1.95 W mK 21

“…2 Recently, there has been a considerable interest in stronger, lighter, flexible, and thermally and electrically conductive materials for aerospace applications. [5][6][7] It has been reported that CNT multi-yarn-based products may meet these needs in the applications requiring high electrical and thermal conductivities, flexibility, and mechanical strengths. [6][7][8][9] CNT yarns are arrays of CNTs which are twisted together in a single dimension.…”

Tensile behavior of carbon nanotube multi-yarn coated with polyester

The behavior of a carbon nanotube (CNT) multi-yarn consisting of 30 yarns and coated with a thin layer of polyester is investigated under tensile loading condition. The coated and uncoated CNT multi-yarns are loaded until fracture occurred inside a scanning electron microscope. In situ photographs were undertaken to investigate the helix angle, diameter, yarn twist, and damage and failure mechanisms. The coated CNT multi-yarn has a higher ultimate tensile strength than the uncoated counterpart. The coated multi-yarn fails at a single location and remains tight after the failure. The uncoated yarn fails at multiple locations along its length and also unravels. The adhesive coating adheres to the CNT yarn surface and does not penetrate into the yarn. These results provide insights into how CNT multi-yarn would behave when used as the reinforcement in the nanocomposites.
