N2 - Double cantilever beam (DCB) specimens were used to study mode I interlaminar fracture of unidirectional carbon fiber/epoxy composites. An improved analytical model was introduced to analyze the crack opening displacement {COD) of the DCB specimen. Theoretical values of COD were compared with those measured by moiré interferometry to evaluate an effective interlaminar tensile modulus and strain in the vicinity of a crack tip. The results showed that the modulus plays an important role in increasing the values of COD, and that there is a correlation between the modulus and the strain.
