Post Construction Materials   Posted on: Thu Nov 21, 2013 7:32 am
I was wondering about what materials can be used for in orbit habitat construction, and where one could find information about materials used. I mean books or journals.

Is most of this information confidential and guarded by space agencies and private companies?

More specifically I was wondering about plastics, and how much are they utilised if at all in the construction of hulls or external covers.

Google is your friend. Most general information can be found from there, including book descriptions. From that you can find the proponent agencies and manufacturers that you can contact to try to get specifics. Even private, semi-secretive companies like Bigalow should be willing to describe how they intend to construct their habs.

In general, most stuff that has or is on-orbit uses an aluminum alloy rigid pressure hull with many layers of aluminum mylar insulation with a smaller number of layers of a dacron/nylon fabric as a protective covering.

I am not sure, but it seems like carbon fiber, and graphene would make a good wall, as carbon has the radiation reflecting properties, and is tough as nails.

they have recently begun making long "Strings" of graphene, that can be woven into a lattice,

this could be flexible, and incredibly tough while also being wires.

I imagine one day a ships hull will also be it's power supply/supercap and computer.

Also there is this - http://en.wikipedia.org/wiki/Radiation_ ... _shielding

So a composite of many materials absorbs many types of radiation...

So some type of mix of rigid, high tensile, radiation absorbing and high hardness values is needed.

1- Impact
2- radiation
3- stress
4- weight
5- duel usefulness

It's going to be... a while. Engineers are a notoriously conservative bunch.

Doesn't matter. The procedures and requirements for certifying a material or fabrication technique for aerospace and esp. for commercial aircraft are... laborious.

Yeah at some point someone will, but don't hold your breath.
