Activated carbon is also called activated charcoal and the two can be used interchangeably. On the other hand, metals, plastics, and most common materials have the same properties in every direction. A metal component would be more likely to yield slowly versus fracturing quickly at its failure limit as carbon fiber does. Carbon fiber, on the other hand, will not permanently deform below its ultimate tensile strength, so it effectively has no yield strength. Carbon fiber-reinforced composite materials are used to make aircraft and spacecraft parts, racing car bodies, golf club shafts, bicycle frames, fishing rods, automobile springs, sailboat masts, and many other components where light weight and high strength are needed.The only limit to what carbon fiber can produce is the imagination of the person who intends to use it. The tensile strength of specimens with the reinforcement oriented at 0° is governed by the tensile strength of the fibers, while for the 90° ones the specimens fail by crack propagation through the matrix and/or the fiber/matrix interface 19,21.
