Standard test methods for delamination resistance of composite materials: Current status

This paper presents a survey of the current status of test methods for the measurement of delamination resistance of composite materials, with particular emphasis on the work performed in this area by ESIS, the European Structural Integrity Society. First, existing mode I fracture test standards are described. We then present work currently underway, both to extend the range of application of these mode I tests and to standardise mode II, mixed mode (I/II) and mode III tests. Finally, we discuss tests to characterise fatigue crack propagation.
