NOVELTY - Preparing polyethylene glycol repaired graphene reinforced aluminum matrix composite involves weighing 0.5-4% graphene, 2-50% polyethylene glycol and the balance aluminum metal powder as raw materials according to the mass fraction. The graphene, polyethylene glycol and aluminum metal powder weighed are placed in a ball mill jar, and the mixed powder obtained by ball milling for 0.5-7 hours at a speed of 100-250 revolution per minute is used. The mixed powder obtained by ball milling is placed in a cold press mold for cold pressing to obtain a polyethylene glycol-graphene/aluminum preform. The polyethylene glycol-graphene/aluminum preform is placed in a vacuum furnace, heated to 350-380 degrees C and held for 2-2.5 hours, and then heated to 450-490 degrees C for 1-1.2 hours, and polyethylene glycol repair graphene/aluminum is obtained. USE - Method for preparing polyethylene glycol repaired graphene reinforced aluminum matrix composite. ADVANTAGE - The method enables to prepare polyethylene glycol repaired graphene reinforced aluminum matrix composite which makes the structural integrity of graphene greatly improved, and a good interface connection is formed, which greatly improves the overall performance of the material, comprehensive performance of graphene reinforced aluminum matrix composites is excellent. DETAILED DESCRIPTION - The obtained polyethylene glycol repaired graphene/aluminum preform is prepared by a pressure infiltration method, a pressureless infiltration method, a powder metallurgy method or a discharge plasma sintering method to prepare a polyethylene glycol to repair the graphene-reinforced aluminum base composite material.
