Abstract

Composite repair is an integral and critical aspect in the service and maintenance of growing fleets in the civil aerospace, automotive, and marine composite–vehicle industries. Bonded repair and scarf repair are particularly attractive from strength restoration and technological standpoints, allowing one-sided access while only minimally affecting the outer shape of the structure. Mechanics of composite scarf repair under tensile loading, with and without overplies, were examined for the ply orientations of nontraditional patches. Three-dimensional ...
