Base-Mediated Depolymerization of Amine-Cured Epoxy Resins.

ABSTRACT: Carbon fiber-reinforced epoxy composites are used in multiple industries, including aerospace, automotive, and wind energy applications, due to their excellent strength-to-weight ratios and tunable material properties. Fortunately, recycling strategies for carbon fiber-based composites are emerging, with the primary focus on the recovery of fibers due to the cost and energy intensity in their production. In addition to fiber recovery, there is an opportunity to recycle the epoxy components such that ideal recycling strategies would yield both fibers and epoxy monomers for reuse. To that end, here we examine potassium tert-butoxide-mediated cleavage of C-O and C-N bonds in amine-cured epoxy resins. We accomplish this via developing model compounds that reflect both C-O and C-N linkag
