| Outline of Final Research Achievements |
This study has developed a nondestructive evaluation method of the laminate structure of carbon fiber reinforced plastic (CFRP) on the scarfed surface by utilizing eddy current, aiming for an automation of the scarf adhesive repair for huge structures such as aircraft composed of CFRP. The technique able to automatically characterize the fiber orientation and to extrude the shape of the patch of respective laminate layer on the scarfed surface, which is important in scarf repair, was developed by utilizing Eddy current testing with a mutual induction differential type probe. Since the adhesive repair is performed not depending on the advanced skill and experience of professional repairmen with this technique, it is expected that the repair of huge structures composed of composite materials could be more reasonable and easier.
