Abstract

Production methods for producing a fiber-reinforced metal component having a metal matrix which is penetrated by a plurality of reinforcing fibers are provided. One method includes depositing in layers reinforcing fibers in fiber layers, depositing in layers and liquefying a metal modelling material in matrix material layers, and consolidating in layers the metal modelling material in adjacently deposited matrix material layers to form the metal matrix of the fiber-reinforced metal component. Here, the metal component is formed integrally from alternately deposited matrix material layers and fiber layers. An alternative method includes introducing an open three-dimensional fiberwoven fabric consisting of reinforcing fibers into a casting mold, pouring a liquid metal modelling material into the casting mold and consolidating the metal modelling material to form the metal matrix of the fiber-reinforced metal component. Here, the metal component is formed integrally from the consolidated metal modelling material and the reinforcing fibers.
