Abstract

The interfacial relationship between a glass fiber bundle and epoxy resin is investigated both experimentally and computationally. A cylindrical notched specimen with a single bundle of fibers along the axis is created to observe debonding behavior. All specimens reached a critical stress value and exhibited debonding to some degree. All material properties are obtained experimentally. The Johnson-Cook failure model is used to simulate the experimental results. The computational model exhibits realistic stress distribution as well as calculates element deletion to simulate interfacial debonding. Simulation refinement will be necessary, especially at the interface, to produce more explicit results.
