LIGHTWEIGHT STRUCTURE ESPECIALLY FOR AN AIRCRAFT AND METHOD FOR MAKING SUCH A STRUCTURE

摘要

An additional fiber reinforced layer reduces crack propagation in a lightweight structure of an outer skin adhesively banded to a reinforcing frame for this purpose the additional fiber reinforced layer is interposed between the outer skin and the frame and adhesively bonded to the outer skin and to the frame. The additional layer 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 additional layer to the outer skin and to the reinforcing frame.
