Mode II Interlaminar Fracture Toughness of Flax/Glass/Epoxy Hybrid Composite Materials: An Experimental and Numerical Study

The mode II interlaminar fracture toughness characteristics of flax/glass/epoxy hybrid laminates were experimentally and numerically examined. Three types of hybrid composites that are made of flax (F) and glass (G) and with different layup sequences (i.e., Hybrid I [0 G/0 F]8S, Hybrid II [04G/04F]S, and Hybrid III [04G/(90/0)2F]S) were investigated. The experimental results obtained from end notch flexural tests showed that both the mode II...
