(I'm not a material engineer so I apologize if any part of this post is idiotic.) The main problem with carbon nanotubes is the difficulty with growing them long enough to be of any use. After doing some research, I found a site about carbon nanotube rings. So it got me thinking, why not, instead of trying to grow them long and interweaving them, form rings out of them and interlock the rings together. This would make sort of like a nanotube chainmail, with each nanotube ring being interlocked with many other rings. Here is the site about rings: http://www.research.ibm.com/nanoscience/rings.html And they also have this interesting pdf. If you look in Figure 1e you can see two interlocking nanotube rings, so interlocking them is possible. http://www.research.ibm.com/nanoscience/Martel_Rings.pdf If this could work, then they wouldn't need to be made nearly as long, and one would think you would still get much of the mechanical strength because you have to break the bonds between the carbon atoms (which is the strong part) to pull the rings apart. What do you guys think?
