STRUCTURAL INTEGRATED REPAIR METHOD AND SYSTEM TOOL DEVICE FOR REPAIRING DELAMINATED COMPOSITE STRUCTURES

摘要

A system for repair of damaged holes in composite structures incorporates a repair system tool device having a sleeve sized to be closely received in a hole in a composite structure. The sleeve has a central bore for receiving parent resin and an array of orifices for radial expulsion of the parent resin into the hole. A caul plate seals the central bore and a vacuum bag covering the caul plate is sealed to the surface of the composite structure. Introduction of vacuum in the vacuum bag provides a differential pressure for infusion of resin from the orifices in the sleeve into delaminations extending from the hole.

1. A system for repair of damaged holes in composite structures, said system comprising:
a repair system tool device having a sleeve sized to be closely received in a hole in a composite structure, said sleeve having a central bore for receiving parent resin and a selected array of orifices for radial expulsion of the parent resin into adjacent delaminations in the hole; a caul plate sealing the central bore; a vacuum bag covering the caul plate and sealed to a surface of the composite structure, wherein introduction of vacuum in the vacuum bag provides a differential pressure for infusion of resin from the orifices in the sleeve into delaminations extending from the hole.
