Abstract
The present invention is a low cost carbon fiber-coating produced via a precursor/solvent solution and the methods and processes for fabricating such a carbon fiber-coating. The carbon fiber-coating comprises a fibrous substrate or fabric material and a carbon coating. The carbon coating prior to carbonization, is comprised of a coating solution made of a precursor dissolved directly within a solvent. Fabrication is achieved by first desizing the fibrous substrate, second immersing the desized fibrous substrate in the coating solution, third evaporating the solvent and curing the precursor via a low temperature pyrolysis in preferably an inert atmosphere, and fourth carbonizing the coating via a high temperature pyrolysis. These steps can be repeated as necessary, depending on the desired final thickness of the carbon coating. Multiple applications of the carbon coating can be used to provide limitless final coating thickness.
