Mode I and Mode II Delamination of Thermosetting and Thermoplastic Composites

Source

A study of the delamination behavior of three classes of composite material is described: glass/epoxy, graphite/epoxy, and graphite/PEEK (polyetheretherketone). Mode I loading was applied to double cantilever beam (DCB) specimens of two thicknesses, while three different types of mode II specimen were tested: end-notched flexure (ENF), end-notched cantilever beam (ENCB), and cantilever beam enclosed notch (CBEN). The latter was developed specifically for this study and is described in detail. A mixed mode specimen is also described. Results from both static and fatigue tests are discussed in terms of fracture mechanics values.
