Mode I interlaminar fracture was studied using double cantilever beam (DCB) specimens of unidirectional carbon fiber/epoxy composites. An improved analytical model was introduced to analyze the crack opening displacement (COD), compliance (C) and fracture toughness (Gi) as a function of the modulus at the vicinity of a crack tip. The COD solution was derived and compared with the COD profiles measured by moire interferometry. The result showed that the COD solution can predict all the important qualitative features of the measured COD profiles; also, the quantitative agreement was sufficiently good. It is found that the modulus plays an important role in increasing the values of COD, C and Gi.
