Adhesively bonded composite repairs in marine applications and utility model for selection of their nondestructive evaluation

During the last half century, the use of composite materials and structures has been increasing within many industries: aerospace, automotive, civil, marine, and railway engineering, wind power generation, and sporting goods, to name a few. There is, however, only a small open literature base concerning adhesively bonded composite repairs, primarily originating from within the aerospace industry. Moreover, little work has been done toward the optimization of repairs on marine composite structures, despite a growing number of such applications. Few decision-making procedures leading to the undertaking of composite repairs have been articulated. Among these, the selection of the most appropriate nondestructive evaluation (NDE) scheme is acknowledged as an important aspect in determining the extent and the type of repair, and ultimately assessing its quality. Such selections of NDE technique(s) currently appear to be largely based upon qualitative engineering judgment, which is likely to lead to long-term sub-optimal remedies. An open literature review of various repair schemes and the parameters that affect their mechanical properties is undertaken, and conclusions on adhesively bonded composite repairs for marine applications are summarized.
