Layers of the vessel wall
The wall of a vessel is usually built from several layers with different jobs, for example a liner that keeps the fuel in, a load-carrying layer around it and an insulation on the outside. The layers are given from the inside outwards: the first one lies on the reference surface of the vessel, which is the surface its cylinder radius and its domes describe, and every further layer lies on the one before it.
Each layer names the sheet-based structural element that carries its material and its thickness. A layer has neither a uID nor a name of its own, so its place in the list is the only thing that tells it from the others, and the order is therefore part of the data rather than a matter of taste.
The excerpt is the wall of the pressure vessel of the example: an aluminium liner of 1.2 mm with a carbon fibre overwrap of 8.5 mm on top of it.
