|The next great frame material???
"The magic substance that appears likely to literally hold the space elevator concept together is the carbon nanotube.
A ribbon 62,000 miles (100,000 kilometers) long made of carbon nanotubes would be some three feet (less than a meter) wide and thinner than a newspaper page. But that ribbon would be hundreds of times sturdier than steel and one-fifth the weight.
Carbon nanotubes are getting extensive in-the-lab looks. More importantly, predicted ultra-strength properties of the material appear to be coming true."

|Carbon nano tubes would be used as reinforcement to a composite matrix, just like CF is today (as was kevlar and fiberglass). The strength and weight would improve SLIGHTLY over current systems. Only Popular Mechanics/Popular Science would predict miracle improvements, not any respected materials person. Cost? You don't want to think about it for many years!|| |
