A mold for manufacturing products made of composite materials, which comprises at least one functional portion made of a composite material joined to at least one interface made of a composite material which projects at least partially around the functional portion, said mold being provided with one

대표청구항 ▼

1. A process for manufacturing products made of composite materials, comprising the steps of: arranging one or more substrates in-a cavity formed between at least one mold made of a composite material and a further mold;hermetically closing and tightening the at least one mold and further mold together with screws inserted into bushings incorporated in the mold and further mold, wherein the bushings in either the mold or the further mold are threaded;evacuating the cavity and injecting resin into the cavity at a pressure of between 0.5 bar and 3.5 bar, so that the one or more substrates are impregnated by the injected resin;placing the closed and tightened mold and further mold into an oven or an autoclave;heating the mold and further mold to cure the resin of the one or more impregnated substrates arranged in the cavity to form a final product,wherein said process does not employ a press. 2. The process according to claim 1, wherein the mold is heated to a temperature of between 25° C. and 70° C., before injecting the resin. 3. The process according to claim 1, wherein the resin is injected into the cavity at a pressure lower than 2 bar and equal to or greater than 0.5 bar. 4. The process according to claim 1, wherein during the evacuation, the pressure in the spaces of the cavity which are not reached by the resin is lower than 0.5 bar. 5. The process according to claim 1, wherein after the cure of the resin, the mold is cooled and opened at a temperature of between 40° and 70° C. 6. The process according to claim 1, wherein in a preliminary step the mold is manufactured by arranging and curing a plurality of layers of fibers on at least one master comprising a template of at least one portion of a product to be manufactured with the mold, wherein the fibers of said layers are pre-impregnated with a resin before they are arranged on the master. 7. The process according to claim 6, wherein one or more bushings are arranged on the master before arranging the layers or are arranged between two layers during their arrangement on the master. 8. The process according to claim 7, wherein the bushings are inserted on one or more pins projecting from the master or from a reference surface which projects at least partially around the master. 9. The process according to claim 1, wherein the further mold is comprised of a composite material. 10. The process of claim 1, wherein the injecting of the resin into the cavity is at a pressure of between 1.5 and 2.5 bar. 11. The process of claim 4, wherein the pressure is between 0.001 and 0.02 bar. 12. The process according to claim 6, wherein the plurality of layers of fibers is carbon fibers. 13. The process according to claim 1, further comprising injecting the resin through one or more injectors screwed into one or more additional threaded bushings incorporated in the mold before injecting resin into the cavity. 14. The process according to claim 1, further comprising evacuating the cavity through at least one suction mouth screwed into at least one additional threaded bushing incorporated in the mold before evacuating the cavity. 15. The process according to claim 1, further comprising extracting the final product from the cavity using one or more extractors screwed into one or more additional threaded bushings incorporated in the mold before heating the mold.
