With its light weight and excellent engineering properties, in the form of high modulus and high strength fiber materials it was initially developed for aircraft and aerospace use. Despite initially high expectations and the remarkable scientific and technical fertility of the domain where we have seen the introduction of cellulosic, PAN, pitch and mesophase pitch fibers, and more recently vapor grown fibers, each of them initiating an impressive development, the commercial success was not immediate and it experienced successive up and downs.

An increase in the comonomer content reduces the optimum time required for thermoxidative stabilization and improves mechanical properties of the carbon fibers. However, it reduces the yield of carbon fibers . The general understanding based on the results reported by various workers  is that about 25 mol% is the most appropriate content for acidic comonomers.
