Full field warpage profiles of the co-cured composite T section structure are measured using the digital speckle correlation method. Both the measurement principle and the optical calibration method are introduced in detail. The shape profile from the side view and the underneath view of the composite T structure are measured, respectively. Finally, the whole warpages of the T section are obtained using image linking technology. These results will play an important role in designing and manufacturing of composite T section structures.
