Abstract
a method for manufacturing a part made of composite material includes the steps of placing, in a mold, a fibrous preform including reinforcing fibers and being resin-impregnated, positioning a prefabricated element in the mold in contact with the fibrous preform at a predefined location of the fibrous preform, the prefabricated element having a predefined form and being produced in composite material comprising partially polymerized resin, compressing the assembly formed by the fibrous preform and the prefabricated element in the mold, heating the assembly formed by the fibrous preform and the prefabricated element in the mold to polymerize the resin and thus binding the prefabricated element with the fibrous preform in order to form the part made of composite material.
