Abstract

An analytical model was employed to study mode I interlaminar deformation in double cantilever beam specimens of unidirectional carbon fiber/epoxy laminates. The crack opening displacements experimentally determined by moiré interferometry were compared with the model to evaluate the interlaminar tensile modulus and strain distribution ahead of the crack front. The findings showed that the modulus makes an important contribution to increasing the value of crack opening displacement, and that the strain distribution was dependent on both the modulus and thickness of the specimen. Also, a specific correlation was recognized between the modulus and the maximum strain evaluated at the crack tip.
