Abstract:
A method of producing a fiber-reinforced metallic building component with a complicated three-dimensional final geometric shape, characterized by the following process steps:A) metal-coated SiC fibers (4, 5, 6) are applied in a desired number, distribution and orientation to a metallic sectional piece (1, 2, 3) having a simple geometric shape different from the complicated three-dimensional final geometric shape, and the fibers are then held without restraint by a metallic counterpart piece (7, 8, 9) secured on the sectional piece (1, 2, 3); B) the unit (10) of the sectional piece, the fibers and the counterpart piece (2, 5, 8) undergoes plastic deformation into the final geometric shape, in vacuo between mold halves (12, 13) under elevated pressure and elevated temperature at which no mentionable bonding of the fibers (5) to one another or of the fibers (5) to the sectional piece or to the counterpart piece occurs; and C) by further increasing the pressure and/or temperature after the step B), the unit (10) is compressed further between the mold halves (12, 13) and undergoes consolidation to a monolithic part (11, 15) by diffusion bonding and/or welding, whereby the monolithic part, either alone or bonded to other parts, forms the building component (16), after cooling and removing the monolithic part from the mold halves (12, 13).
