Claim 0:
1. A method of aerobic depolymerization of fiber-reinforced polymer (FRP) composites, the method comprising:
providing a fiber-reinforced matrix for recycling, wherein the fiber-reinforced matrix for recycling includes a monomer repeat unit having the following formula:, treating the fiber-reinforced matrix with a pretreatment solvent to permeabilize the FRP matrix;
degrading the FRP matrix under oxidative acidic peroxide conditions with a matrix digest solution that includes one or more catalysts and an oxygen source as a terminal oxidant to recover fibers at a first predetermined temperature, the one or more catalysts including MnCl2; and
removing the fibers from the matrix digest solution after the fiber-reinforced matrix has been solubilized; and
harvesting resin monomers.
