Abstract (en)

[origin: EP0799951A1] The method consists of sticking a layer of carbon fibre cloth onto a structure reinforcing surface (4). Firstly the reinforcing surface is prepared and then coated with an epoxy resin layer in the fluid state. A dry flexible cloth (3), constituted from carbon fibres, is placed onto the resin layer still in the fluid state. A sufficient pressure is exerted on the cloth to impregnate the resin and equalise the resin film. The carbon fibre cloth has the shape of a band (7) which extends in a longitudinal direction (X). The carbon fibres form a continuous wire chain parallel to the longitudinal direction and a transverse wire weft.
