Abstract
Edge delamination refers to those delaminations, which arise at the free edge of a laminate. Although edge delamination in advanced laminated composites is a well-documented phenomenon, the repair of edge delamination is still a gray area. This paper presents an effective novel repair approach to repair edge delamination. Special repair tools have been designed and fabricated for this purpose. It also highlights the fabrication of artificially edge delaminated Carbon Fiber Reinforced (CFRP) specimens. Repair strengths have been evaluated by compression tests and Ultrasonic C-scan is used for validation of the repair scheme. From the tests it has been observed that the repair scheme has no bearing on the location of edge delamination and stacking sequence.
