Interfacial mechanics of fiber push-out test:nano-indention technique and cohesive element modeling

摘要：

　　The fiber push-out test is a basic method to probe the mechanical properties of the fiber/matrix interface of a fiber-reinforced composite.In this paper,the interfacial mechanical properties of carbon fiber/epoxy composites are analyzed effectively combing nano-indention technique with cohesive element modeling.Based on the load-displacement curve obtained from the nano-indention experiments,the interfacial shear strength is calculated about 13.7MPa.Furthermore,the finite element method (FEM) model of a fiber-reinforced composite is built in software ABAQUS,in which cohesive zone model is chosen to represent of carbon fiber/epoxy composites interface.The computed results are consistent with experiment data.
