How applicable are developments in carbon fiber like this in rocket body creation:

Or this article on cheaper stronger aerogels:

A strong aerogel would seem a good way to combine the required insulation and lightweight structure when samwidged between two carbon fiber skins.

I agree with the article. I would also add that whenever a country legalized porn or the internet is introduced the number of rapes soon drops. Japan used to have the lowest rates of child abuse in the world they also had lots of animated child porn called Lolicon and shotocon, so they banned it like a civilized country and the rates of child abuse soon raised to the levels seen in the rest of the developed world.

What about using internal struts spanning the fuel tank like a crossbeam instead of two skins.
