Abstract From the Canadian patent

A composite structure consists of two external skins (2, 3) and of an internal core (1) between them wherein a portion (6) of one of the external skins (2) has to be replaced, with pressure from a counter-form (8) and suction. The repair is accomplished by piercing a vent hole (14) in the opposite external skin (3) in order to discharge the air in the cells of the core (1), which improves adhesive bonding of the new portion (6) on the core (1).
