Abstract

Abstract : Vitrimer epoxy resin is a newly developed resin with bond exchange reaction, which has potential applications in the field of recyclable fiber composites. The force-displacement curve of T700 carbon fiber monofilament pulled out from Vitrimer epoxy microdroplet was obtained by the microdrop test, and the interfacial shear strength of the composite system was obtained. Based on the cohesive contact theory, the finite element model (FEM) of the micro-drop test was set up. The calculated force-displacement curve is consistent with experimental data. The fracture strength and parameter characterization of the interface between Vitrimer epoxy and carbon fiber composites are further discussed.
