It is as strong as steel with a fraction of the weight. Carbon Fiber consists of mainly bonded carbon atoms. For example, the fibers’ long axis consists of particles that have been bonded together and aligned. Following this, a yarn is created by twisting several thousand of the threads together. Finally, a piece of fabric is woven from the yarn.
