Abstract
The adhesion of reinforcing fibers to the matrix is vital for the load transfer within a reinforced composite. Being able to impart remendability to the fiber/epoxy interface would increase its material lifetime. Positive results have been obtained by employing the Diels-Alder reaction in a composite of furan-functionalized epoxyamine polymer and maleimide functionalized glass fiber. Microdroplet pullout testing has shown a healing efficiency of 40% after complete interfacial failure. The interfacial strength of the composite and the healing efficiency on a larger scale were determined through the use of Single Fiber Fragmentation and cyclic fatiguing. Close to 100% of the interfacial shear strength (IFSS) was recovered in samples when little damage was introduced. Up to 60% healing efficiency was seen in these samples, with up to 48% healing efficiency seen in samples that had lost a majority of their initial interfacial strength.
