PROBLEM TO BE SOLVED: To provide a method of acquiring damage tolerance by disposing tear straps in aircraft skin.SOLUTION: A method comprises embedding tear straps in a metal aircraft structure (210) having a fully formed contour and thickness. The tear straps comprise strips of fibers (200) that are substantially stronger and stiffer than the metal aircraft structure. The fibers (200) are embedded inside at least one surface (212, 214) of the metal aircraft structure (210) via ultrasonic consolidation.SELECTED DRAWING: Figure 2B

    【課題】航空機外板にテアストラップ(tear strap)を設けて、損傷許容性を得る方法を提供する。【解決手段】成形完了後の輪郭及び厚みを有する航空機金属構造体(210)にテアストラップを埋設することを含む。前記テアストラップは、前記航空機金属構造体よりも相当に高強度かつ高剛性の繊維(200)の条片からなる。前記繊維(200)は、前記航空機金属構造体(210)の少なくとも1つの表面(212、214)の内側に超音波接合を用いて埋設される。【選択図】図2B
