The present invention relates to on-site repairs of a composite structure ( ) such as an aircraft structure in which a concave recess ( ) is machined in the damaged zone, a non-polymerized composite part ( ) is set into said recess and part ( ) is polymerized under pressure using tooling ( ) comprising a stack of plates ( ) that increase the pressure applied to the composite part. The present invention thus obtains invisible repairs with mechanical characteristics that are similar to those of the initial structure.
