Abstract
A method for manufacturing of a part made of composite material including pre-compacting to a predetermined shape of a mixture of a first thermosetting resin with discontinuous long fibers so as to form a first preform, pre-curing the first preform until an intermediate conversion stage corresponding to a solidification of said first resin, contacting the first preform with a second preform including a fiber structure of continuous fibers impregnated with a second thermosetting resin, polymerizing the first and second preforms so as to form a part made of composite material including a body made of composite material including reinforcement made of continuous fibers consolidated by an organic matrix provided with a portion made of composite material including reinforcement made of discontinuous long fibers consolidated by an organic matrix.
