In this study, the effect of interface fiber orientation on delamination initiation and growth of the end
notch flexure (ENF) specimen was investigated. The ENF specimens with stacking sequences of [012//012] and
[011/90//012] were manufactured by the hand lay-up method and tested based on the ASTM standard. Experimental
results show that the interface fiber angle has a significant effect on the initiation and propagation of delamination
behavior of ENF specimens. The initiation values of the critical strain energy release rate (SERR) of ENF specimens
with 0//90 interface are lower than that of specimens with 0//0 interface. In addition, the specimens with 0//90 interface
have a stable crack growth.
