Abstract
A method for manufacturing a machine structural element from a molded composite material includes manufacturing of an abradable layer made integrally from the material of the element. The method consists in adding a filler material to the resin at the surface to be made abradable, the filler material being able to disintegrate, such as e.g. transitioning to vapor phase, during the heat treatment of polymerizing the resin in order to create porosity inside the layer. The porosity thus created provides the relevant surface with properties of abradability.
