Abstract: Disclosed are a method and an apparatus for repairing composite materials using a solvation process, in which, in the repair of composite materials comprising a matrix resin and a filler fiber, a solution capable of depolymerizing the matrix resin is provided to a portion to be repaired of the composite material to depolymerize the matrix resin. By removing the matrix resin constituting the composite material by solvating it with a solvent while leaving the internal filler fibers, it is possible to secure continuity of the fiber skeleton of the composite material even after the repair, perform very easy repair, and minimize damage to the fiber skeleton.
