Composite carbon foams were prepared by mixing tannin-based resin with various graphite powders in an effort to improve the thermal conductivity relative to pristine carbon foams in order to use them as hosts for phase-change materials. It was found that using graphite powder with smaller particle sizes resulted in foams with a higher bulk density than those prepared with an equal amount of larger graphite particles, this increased density resulted ...
The authors have investigated the use of silver nanomaterials as a filler in epoxy resin in an effort to identify a composite resin with a high thermal conductivity for application as a thermal interface material. It was determined that the addition of silver nanoparticle and silver nanowires both increased the thermal conductivity of the resin, but the silver nanowires caused a much more drastic increase. It was found that by ...
The authors present a method of preparing an aluminum shoe mold by a novel process called vacuum sealed casting. It was determined that the prototype shoe should be made of a resin, and then the mold should be made of aluminum. A composite resin was chosen such that the thermal conductivity, dimension accuracy, and wear resistance were greater than those of the pristine resin. The use of the aluminum mold ...
The authors describe a synthesis method for a series of pulverized expandable graphite (pEG)/melamine-formaldehyde (MF) resin core-shell structure particles. The particles are also added into rigid polyurethane foams (RPUF) to characterize the flame-retardant, mechanical, and thermal insulation properties of the RPUF/pEG-MF composites. It was found that the pEG/MF particles showed good flame-retardant performance in the composites by providing a physical barrier effect....
In this study, various filler loadings of thin graphite sheets were added to epoxy adhesives to improve thermal conductivity. Natural graphite powder and graphite nanoflakes were used as reference fillers in the same resin, and the thermal conductivity of each filler was measured with a TPS thermal constants analyzer based on the transient plane source (TPS) method. Results showed that the graphene sheets enhanced the thermal conductivity by more than 22 ...
