1. A method for recycling matrix residues, the method comprising:
degrading a target epoxy to form matrix residue materials;
collecting the matrix residue materials; and
adding the matrix residue materials into a polymer-forming formulation, the polymer-forming formulation including multifunctional anhydride monomers and polyfunctional co-reactant monomers, wherein the matrix residues are a filler for the polymer-forming formulation.
