Keywords: interlaminar fracture toughness, laminate, energy release rate

The effects of moisture on the interlaminar fracture toughness are insufficiently known. The effects of moisture on the mode I and II were studied experimentally on CFRP laminates with DCB and ENF specimens. The moisture increased the insert value significantly whereas the effect on other values was slighter.
