  • Patent number: 9931827
    Abstract: A structural repair includes a tell-tale optical witness that allows the health of the repair to be visually monitored. The optical witness includes a stress sensitive fluorescent dye that shows changes in local strain/stress patterns when the repair is subjected to electromagnetic energy of a particular wavelength. The dyes fluoresce more or less strongly as a function of the local stress/strain.
    Type: Grant
    Filed: May 27, 2015
    Date of Patent: April 3, 2018
    Assignee: THE BOEING COMPANY

  • Patent number: 9604419
    Abstract: A patch for a structure has a rework area with an inconsistency formed therein. The patch comprises a patch body having at least two regions including a fail-safe region and a safe-life region encompassing the fail-safe region. The safe-life region has a mode I interlaminar fracture toughness that is less than the mode I interlaminar fracture toughness of the fail-safe region.

  • Patent number: 9393768
    Abstract: A repair patch for reworking an inconsistent area of a composite structure includes a patch body adapted to cover the inconsistent area and having a first patch region, a second patch region outside the first patch region and a first separation zone between the first patch region and the second patch region, with the first patch region, the first separation zone and the second patch region having increasing interlaminar fracture toughness from a center to an edge of the patch body; and a layer of adhesive for bonding the patch body to the composite structure.

  • Patent number: 9393651
    Abstract: A composite laminate patch for reworking an inconsistent area in a structure has inner and outer control regions possessing differing interlaminar fracture toughnesses for controlling the advance of a disbond in the patch. One or more separation zones in the patch between the control regions aids in diffusing the fracture energy of the disbond as the disbond advances from the inner region to the outer region.

  • Patent number: 8935286
    Abstract: A method and apparatus for managing parts. A number of identifiers is received for an unidentified part. A determination is made as to whether the number of identifiers sufficiently matches a number of corresponding identifiers in a plurality of identifiers in a code stored in a database of codes associated with parts. The code is associated with the part. In response to the number of identifiers matching the number of corresponding identifiers in the plurality of identifiers in the code, a repository storing related information for the parts is accessed to obtain the related information for the part using a code identified for the part.
