A process for the preparation of a semifinished product including a PAEK-based resin and reinforcing fibers, including the stages of: a. preparation of a dispersion including a PAEK-based resin in the pulverulent form dispersed in an aqueous phase including a surfactant; b. bringing the reinforcing fibers into contact with said aqueous dispersion; c. drying the fibers impregnated with dispersion; and d. heating the impregnated fibers to a temperature sufficient for the melting of the resin, so as to form a semifinished product, wherein the surfactant is a thermally stable surfactant. Also, semifinished products capable of being obtained from the process and their use in the manufacture of composite materials.
