研究了单向碳/环氧复合材料的I型和II型抗分层性能。首先，由欧洲骨折组（EGF）的聚合物和复合材料工作组，涉及10个实验室组织的循环练习的结果，介绍。用双悬臂梁（DCB）、端部切口弯曲（ENF）和端部加载劈裂（ELS）试样测量了GI和GIIcat的起裂和扩展值。然后讨论了缺陷类型和试样几何形状对该材料抗分层性能的影响。
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 ofGIcandGIIcat 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.
