IM7 Carbon Fiber is 33% stiffer than standard carbon fiber and about 50% stronger in tensile strength. If you want to build a lighter, stiffer, and stronger part this stuff may be the ticket.
IM7 filaments are smaller in diameter than standard carbon so a 12K yarn nets out in size to about the same as a 6K bundle.
Sold by the running yard it comes rolled on a tube to ensure the fibers properties are maintained through the shipping process. 1 yard is 36" x 50" if you order 10 yards you'll recieve a piece 360" long x 50" wide.
