In a relatively short period of time, carbon fiber has revolutionized the manufacturing industry due to its low weight and excellent structural properties. Carbon fiber is a composite material. Composite carbon fiber is made of a woven carbon fiber that reinforces a polymer resin (usually epoxy) [3]. Carbon fibers themselves are polymers of graphite (which has a hexagonal sheet structure) rolled into a thin filament [2]. Tensile strength (resistance to tearing due to pulling) and Young's modulus (force needed to stretch or compress a material) are extremely high in relation to the weight of the fiber. The internal strength of the carbon fiber lies in the weave structure and the impact resistance comes from the hard plastic polymer shell. This article will focus on the manufacturing process of polyacrylonitrile (PAN) carbon fiber, the applications of carbon fiber in industry, and the future applications of this revolutionary
