Carbon-fiber tape

Carbon-fiber tape is a flat material made of carbon fiber. It weighs one-seventh as much as steel for a given strength. The carbon fiber core lasts longer than conventional steel cable. The material is resistant to wear and abrasion and, unlike steel, does not densify and stretch.[1]

Applications

In June 2013, KONE elevator company announced Ultrarope for use as a replacement for steel cables in elevators. It seals the carbon fibers in high-friction polymer. Unlike steel cable, Ultrarope was designed for buildings that require up to 1,000 meters of lift. Steel elevators top out at 500 meters. The company estimated that in a 500-meter-high building, an elevator would use 15 per cent less electrical power than a steel-cabled version. As of June 2013, the product had passed all European Union and US certification tests.[1]

gollark: As a somewhat more rule-abiding person I mostly don't, although the cost/benefit probably does come out in favour.
gollark: Yes. Quite a lot of people use them anyway and just deal with them being confiscated occasionally.
gollark: Also, I can have internet access all day - my school foolishly banned use of phones during lunch break (not just while eating, during the entire 1 hour 30 minute break).
gollark: I do less pointless busywork, less work generally, have a more comfortable home environment to work in, get to type things instead of foolish "writing", and don't have a 45 minute commute to school, which is all nice.
gollark: I quite like it!
