1.1 This test method describes the determination of the mode II interlaminar fatigue growth of unidirectional fiber-reinforced polymer laminates under cyclic mode II shear loading using the end-notched flexure (ENF) test. 1.2 This method is limited to use with composites consisting of unidirectional carbon-fiber and glass-fiber reinforced laminates. This limited scope reflects the experience gained in round robin testing. This test method may prove useful for other types and classes of composite materials; however, certain interferences have been noted (see Section 6).

The data is being evaluated and developed for use in damage tolerance in the composites industry. There is a need to establish test methods and proper ways to measure and reduce data.
