摘要： Disclosed is a chemically decomposable thermosetting resin composition for recycling a fiber-reinforced composite, including an epoxy resin, a multifunctional glycidyl-ester-based compound, an additive having a hydroxyl group on at least one of terminals of a main chain thereof, and an acid-anhydride-based curing agent, thus exhibiting excellent chemical decomposition performance in a basic solution and a high glass transition temperature. A method of dissolving the thermosetting resin composition is also provided. Thereby, a thermosetting composite material containing a thermosetting resin of the invention enables recycling of carbon fiber through hydrolysis, and thus the carbon fiber recycling industry and the recycled resin industry can be newly expanded. The thermosetting resin can be applied to fields using not only carbon composite materials but also general thermosetting resins, and can be hydrolyzed in a basic solution, which can significantly reduce landfill or disposal costs.
