The method includes the steps of functionalizing a polyaryletherketone (PAEK) polymer, and blending the PAEK polymer with water to form a sizing composition. The method may further include the step of applying the sizing composition to a fiber. The method may further include the step of heating the fibers, coated with sizing composition, for example to between 300 C.-400 C. In some methods, the functionalized PAEK polymer comprises functionalized polyetherketoneketone (PEKK). In yet other methods, the functionalized PAEK polymer comprises sulfonated PEKK (sPEKK).
