Method of Machining Carbon and Graphite foams Disclosure Number 200902291 Technology Summary Machining of graphite foams is very difficult. This invention describes a method to overcome many years of frustration in machining the foams. In order to get the best heat transfer, a very small fin structure is needed. However the act of machining this is very d…

Method for Controlling the Structural Alignment in Carbon Fibers with Naturally High Turbostratic Disorder Using Heterogeneous Nucleation Method for Controlling the Structural Alignment in Carbon Fibers with Naturally High Turbostratic Disorder Using Heterogeneous Nucleation Disclosure Number 201202880 Technology Summary It was discovered that incorporating nanoscale particles of a …

Cooling of Weapons with Graphite Foam Disclosure Number 201002371 Technology Summary A graphite foam that was partially densified with a second material was wrapped around the barrels of weapons. It is evident that by placing a graphite foam wrap densified with a second material around the barrels, the temperature of the barrels can be reduced. This was b…

Polymer Bonded Graphite Foam Disclosure Number 201403425 Technology Summary Ground or "powdered" Graphite foam particles are combined with (and bound by) various polymer systems to yield substantially improved thermal conductivity for applications where improved thermal conductivity is required, i.e. heat- sinks, and situations where heat transfer in a polymer bonded matrix or article is…

Metal-Bonded Graphite Foam Composites Disclosure Number 201102608 Technology Summary For thermal properties applications, the well-known graphite foam technology developed at ORNL has demonstrated remarkable performance when compared to other more commonly used materials such as aluminum and magnesium, for example. Carbon foam has found its way into a bro…

High Capacity Monolithic Composite Si/Carbon Fiber Electrode Architectures High Capacity Monolithic Composite Si/Carbon Fiber Electrode Architectures Disclosure Number 201303023 Technology Summary We demonstrate a low cost, energy dense electrode composed of LCF+Si. Si has been a sought after anode material for years due to its high capacity 3800 mAh/g in comp…

LED North America Receives Exclusive Patent License for ORNL Graphite Foam Technology Light-emitting diode (LED) lamps are increasingly in demand in industrial and commercial applications because of their comparatively low energy consumption, compact size, and long life expectancy. They come with a high price tag, though, so to make them attractive to a broader consumer base, they will have to gi…

Carbon or Graphite Foam Heating Element for Regulating Engine Fluids Automotive engines need to run hotter to meet requirements for better fuel economy and lower emissions, but devices to keep engine fluids from becoming too hot can add weight, cost, and complexity to engine designs. ORNL researchers developed a graphite foam heating element that can eliminate the need for a separate cooler for o…
