摘要

The high strength and modulus of carbon fibers make them useful in the reinforcement of polymers, metals, carbons, and ceramics, despite the fibers' brittle nature. Carbon fibers prepared from polyacrylonitrile (PAN) precursor fibers by conventional techniques have a minimum diameter between 5-7μm. The bulk of production cost incurred during carbon fiber production is due to long heating times required to stabilize and carbonize the precursor fiber.
