Making solvent recovery more cost-effective

Full Recovery of Fracture Toughness Using a Nontoxic Solvent-Based Self-Healing System

Two significant advances are reported for solvent-based self-healing of epoxy materials. First, an autonomic system yielding complete recovery of fracture toughness after crack propagation was achieved by embeddingmicrocapsules containing amixture of epoxy monomer and solvent into an epoxy matrix. Healing with epoxy-solvent microcapsules is superior to capsules that contain solvent alone, and m...

Full recovery of fiber/matrix interfacial bond strength using a microencapsulated solvent-based healing system

Full recovery of interfacial bond strength after complete fiber/matrix debonding is achieved with a microencapsulated solvent-based healing chemistry. The surface of a glass fiber is functionalized with microcapsules containing varying concentrations of reactive epoxy resin and ethyl phenylacetate (EPA) solvent. Microbond specimens consisting of a single fiber and a microdroplet of epoxy are te...
