The invention belongs to the technical field of plastic production and particularly relates to a polyetheretherketone/hollow fly-ash bead/glass fiber composite material and a preparation method thereof. The composite material is characterized by mainly comprising the following raw materials in parts by weight: 80-150 parts of polyetheretherketone, 5-30 parts of hollow fly-ash beads, 5-30 parts of glass fibers, 0.1-1 part of dodecylbenzene sulfonic acid, 0.1-1 part of stearic acid and 0.2-1 part of a silane coupling agent. The preparation method comprises the following steps: grading and sorting fly ash; performing activating pretreatment; blending with resin; extruding; cooling and granulating to prepare the polyetheretherketone/hollow fly-ash bead/glass fiber composite material. According to the composite material, the resin price is reduced, the tensile strength, impact resistance and friction resistance of PEEK (polyetheretherketone) resin are improved, and the rigidity and size stability of the PEEK resin are enhanced; moreover, the preparation method is reasonable in design and has the characteristics of being simple and convenient to carry out, continuous in process, high in production efficiency, low in noise and free of three wastes in the production process.
