摘要:
The present invention provides production methods for producing a fibre-reinforced metal component (1) having a metal matrix (2) which is penetrated by a plurality of reinforcing fibres (3). One production method comprises depositing in layers reinforcing fibres (3) in fibre layers, depositing in layers and liquefying a metal modelling material (4) in matrix material layers (5), and consolidating in layers the metal modelling material (4) in adjacently deposited matrix material layers (5) to form the metal matrix (2) of the fibre-reinforced metal component (1). Here, the metal component (1) is formed integrally from alternately deposited matrix material layers (5) and fibre layers (6). An alternative production method comprises introducing an open three-dimensional fibrewoven fabric consisting of reinforcing fibres (3) into a casting mould, pouring a liquid metal modelling material (4) into the casting mould and consolidating the metal modelling material (4) to form the metal matrix (2) of the fibre-reinforced metal component (1). Here, the metal component (1) is formed integrally from the consolidated metal modelling material (4) and the reinforcing fibres (3).
