In answer to the first part of your question, the strongest metal known is Tungsten -
"Tungsten is the strongest metal known to man at this time. The name "tungsten" is taken from the Swedish word, tung sten, meaning "heavy stone," and is a tough, steel-gray to white metal. Tungsten is known as the metal for making filaments in common incandescent light bulbs. The application takes advantage of the fact that tungsten has the highest melting temperature of any metal. Its temperature can be raised to the point where it glows with a brilliant white light. Most other metals vaporize before they can produce much light." - http://www.firstscience.com/SITE/factfile/factfile3221_3240.asp
Though when difining the toughest material you want a metal that is strong and ductile. The metal may be very strong, but lack ductility - in which case it fractures in stead of yielding when subject to stress.
Tungsten carbide is also very strong and used on the tips of cutting tools. Tungsten is however dificult to work with so other alloys are used as well, where high strength is in important issue.
Fibrous armored material - I assume you are referring to carbon fiber or Kevlar.
I don't know of a reliable way to stop Armour piercing rounds - smart armor has explosive charges that trigger and deflect the projectile.

There is nothing I know of that can stop an Armour Piercing round at this time. The strongest known metal right now is TItanium, I believe. Most tanks rely on layered armour or some sort of "smart" armour in order to stop armor piercing rounds or at least slow them enough to keep them from completely penetrating their armour.

In addition to the tanks hard armored shell and the troops kevlar vests, tanks are equipped with an armor jacket that explodes (over a larger area of the exterior of the tanks), hopefully blowing the incoming assault away.

Nope its just a big rolling coffin it will stop 7.62 but anything else your pushin your luck

interwoven natural spider web. Synthetic copies are not quite there yet. Neither are cost effective.
