Through the addition of synthetic graphite particles and carbon fiber to nylon 6,6 in amounts of 10-40 wt.% and 5-40 wt.% respectively, nylon composites were prepared. These composites were then analyzed using the guarded heat flow apparatus to measure through-plane thermal conductivity. Then the transient plane source (TPS) technique was used to measure the through-plane and in-plane thermal conductivities of the composites to compare to the guarded heat flow apparatus. A ...
Two different types of polyacrylonitrile carbon fibers (Fortafil 243 and Panex 30) were added to thermoplastic matrix (Vectra A950RX Liquid Crystal Polymer) in order to generate carbon fiber/liquid-crystal polymer composites. The in plane and through-plane thermal conductivities of these composites were then evaluated and compared to values generated from a theoretical model, with good agreement. Panex 30 gave higher in-plane thermal conductivity than Fortafil 243 for all volume fractions studied....
Two different types of carbon (synthetic graphite particles and carbon fiber) were added to nylon 6,6 and then these composites were tested using the transient plane source method in order to determine the through-plane and in-plane thermal conductivities. The thermal conductivities were found to be proportional to the volume percent of carbon added. A simple empirical model was also developed in order to estimate in-plane thermal conductivities for a range of ...
Synthetic graphite particles were added to a liquid crystal polymer and then these composites were tested for through-plane and in-plane thermal conductivity using the TPS method. The authors expanded on an empirical model created to determine the relationship between thermal conductivity and volume percent of filler. This empirical model can now be used to approximate the in-plane thermal conductivities for a range of applications....
