Someday soon this new material will need to be joined
By Kirk Cooper on Wednesday, July 25th, 2012
Recently, researchers in Germany reported the creation of “The World’s Lightest Material,” a new carbon-based material they dubbed “Aerographite” (see Figure 1). This material has a reported density of only 0.2 mg/cc, about 75 times less dense than styrofoam. Aerographite is believed to hold great promise for applications requiring high conductivity and light weight. It is also strong yet elastic, able to be compressed up to 95 percent of its thickness then spring back to its original dimensions when the load is removed. In addition, it’s superhydrophobic.
I love hearing about new materials like Aerographite. They stretch the boundaries of what is achievable in strength, energy efficiency, and service temperature. Most of the talk about Aerographite’s uses centers on batteries, filtration, and “wearable computing”. But to get to that point, manufacturers will need help figuring out how to join Aerographite to other materials.
And that’s where EWI comes in. We have already demonstrated the ability to join such wildly differing materials as graphite fiber tows and titanium, or pyrolitic graphite and tungsten alloys.
