Polyether ketone ketone composite material, preparation method and application

The embodiment of the invention provides a polyetherketoneketone composite material and a preparation method and application thereof, and the preparation method comprises the following steps: uniformly stirring clean polyetherketoneketone material particles and clean glass fibers to obtain a stirred material; transferring the stirred material into a hot-press injection molding machine for injection molding, and cooling for molding to obtain an injection molding material; and after the to-be-treated surface of the injection molding material is polished, metal ions are injected, and the polyetherketoneketone composite material with the surface ion injection layer is obtained. According to the embodiment of the invention, the polyetherketoneketone composite material with the surface ion implantation layer is obtained by injection molding of the polyetherketoneketone material and the glass fiber and polishing and implantation of the metal ions into the to-be-treated surface of the material subjected to injection
