General Details
Name:  Ferro-Fibrous
Type (Category):  Armor (Core)
Reference:  TechManual (p. 205)

Description:
A more advanced form of combat armor, ferro-fibrous (and its aerospace/spacecraft analogue, ferro-aluminum) is a military-grade armor significantly lighter than standard armor. Ferro-fibrous achieves its lightweight properties through the wider use of diamond fiber filaments throughout the ceramic and steel layers (standard armor does not incorporate a diamond weave in the steel layer). While this makes ferro-fibrous far more bulky, the weight savings afforded by this armor type for the same level of protection can enable units to mount more weapons and equipment. Of course, this capability must be balanced against the limited internal space left after its installation.

Limited by design (and economics) to military vehicles and BattleMechs, ferro-fibrous armor is available in a variety of popular brand names including Durallex, Kallon Unity Weave, Lexington Limited High Grade and StarGuard.

Game Rules:
Armor is considered structural and cannot be “deactivated” during combat through engine shutdown or pilot/crew injury. Critical hits against any type of ferro-fibrous armor (standard, light or heavy) critical slot have no effect and should be re-rolled.
