Unlike earth-anchored amplitude elevators, the abstracts for lunar amplitude elevators won’t crave a lot of strength. Lunar elevators can be fabricated with abstracts accessible today. Carbon nanotubes aren’t appropriate to body the structure.[1] This would accomplish it accessible to body the elevator abundant sooner, back accessible carbon nanotube abstracts in acceptable quantities are still years away.[2]
One actual that has abundant abeyant is M5 fiber. This is a constructed cilia that is lighter than Kevlar or Spectra.[3] According to Pearson, Levin, Oldson, and Wykes in their commodity The Lunar Amplitude Elevator, an M5 award 30 mm advanced and 0.023 mm thick, would be able to abutment 2000 kg on the lunar apparent (2005). It would additionally be able to authority 100 burden vehicles, anniversary with a accumulation of 580 kg, analogously spaced forth the breadth of the elevator.[1] Other abstracts that could be acclimated are T1000G carbon fiber, Spectra 200, or Zylon. All of these abstracts accept breaking lengths of several hundred kilometers beneath 1g.[1]

The abstracts will be acclimated to body the ribbons which will affix from the L1 and L2 antithesis credibility to the apparent of the moon.[1] The ribbons would be acclimated by the automatic aggressive agent to get from the apparent into orbit.[1] The cartage would be slow, compared to actinic rockets, but it is a acceptable acceleration for appointment cargo.[1]
The ribbons are activity to be decumbent to accident by micrometeoroids from amplitude so one way to advance their survivability is to accomplish a multi-ribbon arrangement instead of one.[1] They will accept arrangement at approved intervals, so that if one area is damaged, the alongside sections would backpack the amount until automatic cartage can appear and alter the missing ribbon.[1] The arrangement would be spaced about 100 km apart, which is baby abundant to acquiesce a automatic climber to backpack the accumulation of the backup 100 km of ribbon.[1]
