Which means OP posted three times, as I am and this is my second post in this thread.
Is air a "material"?
Wyatt Diaz
Hudson Wilson
think of it this way. if you modelled something in CAD or some software like MCNP, if you left a volume blank with no material, would it interpret it as air or a vacuum (assuming you're not given an error)
Ian King
Air is used because otherwise you would have to seal the chambers, adding weight and manufacturing costs as well as the need to periodically refil.
Connor Wright
Fuck no, air would be pointless, as air is highly compressible (you might as well fill it with water, something that isn't highly compressible).
Jayden Richardson
I screencapped the thread at the wrong time so my image was meaningless,
but i still post the question:
If any of you Veeky Forums guys know the difference/similarities between spaced armor and composite armor, do air gaps count as "composite armor"?

^ To reiterate.
James Ward
The 'air gaps' were intentionally added and serve a purpose (rapidly changing densities and elasticity), arguing that they are not part of the composite armor's structure is silly.
Dominic Watson
Air is a component in a material. A material can have many components, including air.
Holy shit people.
Jordan Green
Typically vacuum. Air is considered for physics calculations like wind loads, but it's typically not used in the actual design files. It's not going to list air on the bill of materials.
>Air is used
>is used
Nice weasel with the passive voice there. No one specifically puts air there. It just happens to be there since it's not specifically kept out. It is irrelevant to the function of the armor. Would you say that air "is used" to fill the gaps in a truss bridge?
Jordan Sullivan
>A material can have many components, including air.
True, but that doesn't mean that every structure that doesn't specifically exclude air has air as a component. Air is a material component of hot air balloons. Replacing the air with vacuum would prevent the balloon from functioning. Air is not a material component of spaced armor. Removing the air would not alter the function of the armor.
