Jacob's ladder plate armour

an alternative to chainmail
  [vote for,

A Jacob's ladder is a fun toy that uses straps or ribbons to act as hinges.

My idea is to connect together an array of hexagonal plates with Jacob's ladder ribbon hinges, to form a strong yet flexible armour. This would make an interesting alternative to chainmail.

       The trouble is, a single light cut to the shoulder would sever the ribbon, and then everyone could stop fighting and watch the little plates flipping and tumbling down until all the armour was around your ankles.

       ... which would, itself, be a beautiful sight. [+]

       Why it's beautiful. And you must know that "teal" is the "hot" color right now.

       That's a honey of an illustration.

       [+] for CAD rendering. Is it intended to just flex, or also to flip around like a Jacob's Ladder? (one directional flipping.) If the latter, it seems to be over- constrained.
sninctown, Mar 26 2021

       The hinged plates are just intended to flex, no flipping (sorry to disappoint [pocmloc]). By using the Jacob's ladder hinge you can get large flex angles in both directions using relatively thick plates, and no (or very little) bevel/chamfer on the plates to allow them to hinge.

       Kevlar ribbons and you're good to go.

       //Kevlar ribbons// - why not graphene?

       Why not UHMWPE?

       Neither of those materials are bullet proof.   

       I don't know of any commercially available graphene products.. But UHMWPE is used in bullet proof vests (as well as cut-resistant gloves and other clothing). It's better than Kevlar for this application - both the straps and the plates.

       UHWMPE is a rigid armor. It's used in layered sheets, right? How flexible can it be made?
21 Quest, Mar 26 2021

       I submit that Jacob's Ladder Plot Armor would work almost as well (i.e. quantum immortality)

       //UHWMPE is a rigid armor. It's used in layered sheets, right? How flexible can it be made?//   

       It can be drawn into fibers as fine as spider silk. It's used in fishing line and nets, tents and clothing, climbing ropes, lots of other stuff. Dyneema is one brand name but there are many.
