Abstract
This paper deals with interlaminar fracture testing of unidirectional (UD) fiberreinforced polymer-matrix (FRP) composites. The emphasis will be on the development of standardised test procedures. After defining the terminology, an overview is given of interlaminar fracture toughness testing under different loading conditions. A selection of experimental aspects from the test development is presented in detail. Discussion and conclusions then focus on results from recent research.
