How much energy is required to produce carbon fiber?

The energy required to produce carbon fiber varies, but it typically ranges from 20 to 30 megajoules per kilogram (MJ/kg) of carbon fiber produced. This energy is primarily consumed during the precursor processing, stabilization, and carbonization stages. The overall energy consumption can also be influenced by the production method and the specific precursor materials used. As a result, advances in technology and processes may help reduce this energy requirement in the future.
