LIGHT WEIGHT
A traditional fiberglass reinforced composite using continuous glass fiber with a fiber of 70% glass (weight of glass / total weight), will commonly have a density of 0.065 pounds per cubic inch.
Meanwhile, a CFRP (carbon fibre reinforced polymers) composite, with the same 70% fiber weight, might typically have a density of 0.055 pounds per cubic inch.
INCREASED STRENGTH
Not only are carbon fiber composites lighter weight, but CFRP (carbon fibre reinforced polymers) composites are much stronger and stiffer per unit of weight. This is true when comparing carbon fiber composites to glass fiber, but even more so when compared to metals.
