Sheets Of Carbon Nanotubes

New Hampshire Startup Makes World’s Largest Sheets of Carbon Nanotubes that measure up to three feet by six feet, and they promise "slabs 100 square feet in area as soon as this summer."

"The sheets, which the company can produce on its single machine at a rate of one per day, are composed of a series of nanotubes each about a millimeter long, overlapping each other randomly to form a thin mat. The tensile strength of the mat ranges from 200 to 500 megapascals--a measure of how tough it is to break. A sheet of aluminum of equivalent thickness, for comparison, has a strength of 500 megapascals. If Nanocomp takes further steps to align the nanotubes, the strength jumps to 1,200 megapascals."
