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

A method of pressure forming a brown part from metal and/or ceramic particle feedstocks includes: introducing into a mold cavity or extruder a first feedstock and one or more additional feedstocks or a green or brown state insert made from a feedstock, wherein the different feedstocks correspond to the different portions of the part; pressurizing the mold cavity or extruder to produce a preform having a plurality of portions corresponding to the first and one or more additional feedstocks, and debinding the preform. Micro voids and interstitial paths from the interior of the preform part to the exterior allow the escape of decomposing or subliming backbone component substantially without creating macro voids due to internal pressure. The large brown preform may then be sintered and subsequently thermomechanically processed to produce a net wrought microstructure and properties that are substantially free the interstitial spaces.
