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.

Abstract: For depolymerization of a cured epoxy resin material, used is a composition including a transition metal salt or a transition metal oxide containing a transition metal element (metal element that belongs to Groups 3-12 in the Periodic Table). In the reaction solvent, an oxidation occurs by the medium of the transition metal element so that the cured epoxy resin material may be depolymerized and decomposed. In this manner, it is possible to carry out depolymerization of a cured epoxy resin material at a temperature of 200°C, specifically 100°C or lower very simply and rapidly, and to reduce the processing cost and energy requirement.

Abstract: Provided are a composition for swelling pretreatment of a cured thermosetting resin material before decomposition, including a surfactant and an acidic material, and a method for swelling pretreatment of a cured thermosetting resin material before decomposition by using the same. When carrying out swelling pretreatment of a cured thermosetting resin material before decomposition by using the composition, it is possible to accelerate infiltration of the acidic material into the cured thermosetting resin material and swelling of the cured thermosetting resin material by virtue of the surfactant, and thus to increase the decomposition reactive surface area. Therefore, it is possible to increase reaction efficiency during the subsequent decomposition process, and to increase the decomposition ratio during the same period of time.

Abstract: A cured epoxy resin material is depolymerized by using a composition including a compound represented by the chemical formula of XO m Y n (wherein X is hydrogen, alkali metal or alkaline earth metal, Y is halogen, m is a number satisfying 1≤m≤8 and n is a number satisfying 1≤n≤6), and a reaction solvent, wherein X is capable of being dissociated from XO m Y n and Y radical is capable of being produced from XO m Y n in the reaction solvent. In this manner, it is possible to carry out depolymerization of a cured epoxy resin material, for example, at a temperature of 200°C, specifically 100°C or lower, and to reduce a processing cost and an energy requirement. It is also possible to substitute for a reaction system using an organic solvent as main solvent, so that the contamination problems caused by the organic solvent functioning as separate contamination source may be solved and environmental contamination or pollution may be minimized.
