摘要
The measurement of mode I and mode II delamination resistance of a unidirectional carbon/epoxy composite is examined. First, the results of a round-robin exercise organised by the Polymer and Composites Task Group of the European Group on Fracture (EGF), involving 10 laboratories, are presented. Values of GIc and GIIc at initiation and propagation have been measured using double cantilever beam (DCB), end notched flexure (ENF) and end loaded split (ELS) specimens. The influence of defect type and specimen geometry on the values of delamination resistance of this materials is then discussed. © 1990.
