Magellan's chain

Short poast today to consider alternatives to Zylon or T1100G. Pearson's crew, in 2004, did not know T1100G but had caught wind of Magellan's "M5". This was a honeycomb-like 3-D polymer that, honestly, kind of sucked, stress-limited at 5.7 GPa where Zylon was rocking 5.8 Gpa.

Dupont bought Magellan the following year and with M5 has done... squat. Turns out M5 is expensive to make.

The issue here seems to be that the Aramid family (Kevlar), and UHMWPE (Dyneema), somewhat max out below where Toray's T1100G lives. T1100G is a carbon fibre and as such can do better. Not as well as theoretical M5, but maybe they'll get a theoretical T1100G+.

For these science-fiction cables on the spaceline through TLL1 however, I wonder if we can make smaller segments of M5 at one time that are linked in a chain. One issue here would be the friction of the links between each other. Also the mass will increase for the same length. On the other hand I can see this being easier to manufacture and for those robo-climbers to grab onto.

So maybe from L1 down to the Lunar surface?
