Abstract :
In this letter, we investigated the origin of the interfacial delamination due to uneven curing of ultraviolet (UV) adhesive in the fixing process of a fiber on a V-groove. The analytical ray tracing technique is used to estimate the UV intensity at different locations along the adhesive-fiber interface. Consequently, the unexposed or shaded region in the adhesive layer is determined, through which the interfacial delamination as a result of the reliability test is predicted.
