Abstract
A fiber reinforced strip is adhesively bonded to an outwardly facing surface of a reinforcing frame and to an inwardly facing outer skin surface. Such a strip position reduces crack propagation in a lightweight structure particularly in the outer skin adhesively bonded to the reinforcing frame through the strip. For this purpose the fiber reinforced strip is interposed between the outer skin and the frame and adhesively bonded to the outer skin and to the frame. The strip has reinforcing fibers extending in parallel to each other or the reinforcing fibers are woven into a fabric embedded in a synthetic adhesive bonding material. The embedding of the parallel fibers or of the fiber fabric in the bonding material is performed either prior to the bonding or during the bonding of the strip to the outer skin and to the reinforcing frame.
