Is Tungsten Carbide coated with a layer of high silicon glaze for an outer hull a layer of homemade aerogel insulation and an aluminum inner hull a good combo to use as a space ship hull?
No, the aluminum has to me thick, so you aren't saving anything.
The Tungsten Carbide is the 2nd heaviest armor out there. There is
two new no metal armor with the new plastic shield with Reinforced
byTitanium to help keep hull shape. The mass is cut to less then
25% and less then half the thickness.
