Patent ID: 8475615

Claim:
A method of repairing a wall ( 1 ), notably a composite wall, comprising: a plurality of layers ( 2 ), each layer comprising fibers ( 3 ) extending in a main direction ( 4 ), and having a damaged area ( 5 ) affecting the plurality of layers ( 2 ), said repair method comprising: removing a material by hollowing out the wall ( 1 ) to produce a hollowed out area ( 6 ) encompassing the damaged area ( 5 ), the hollowed out area including a peripheral area ( 7 ) including steps ( 8 ), the height of each step is equal to the thickness of at least one of the layers, each step ( 8 ) defines an interface area ( 9 ) that is coplanar with a junction plane between a lower layer and an upper layers lying below and above said junction plane, the removing step is carried out sequentially to expose each step in succession; producing a replacement part ( 12 ) adapted to block the hollowed out area ( 6 ), the replacement part includes superposed replacement layers having thickness adapted to the height of the steps to cover each level ( 11 ) defined by the steps, the replacement layers include fibers oriented in the main direction of the fibers of the lower layer; and assembling the replacement part ( 12 ) to the wall ( 1 ), the interface area ( 9 ) having a width ( 10 ) greater in the main direction ( 4 ) of the fibers ( 3 ) of the lower layer adjoining said interface area ( 9 ) than said width ( 10 ) in directions other than the main direction ( 4 ).
