Abstract
A method of placing a fastener plate on a structure made of composite material, the structure being obtained by a technique of injecting resin under a vacuum, the technique including placing a fiber preform in a closed mold, injecting a thermosetting resin into the mold, and polymerizing the resin prior to cooling. The method includes mounting a metal fastener plate against a wall of the mold before putting the fiber preform into place, the fastener plate coming into contact with one of faces of the fiber preform while the fiber preform is being put into place in the mold, and the resin becoming deposited between the fastener plate and the fiber preform while the resin is being injected into the mold. The method may be used in particular for fastening equipment on a composite material fan casing of a gas turbine for an aeroengine.
