Patent number: 6698645Abstract: A method of producing fiber-reinforced metallic building components having a complicated three-dimensional geometric shape includes the following steps. First, metal-coated SiC fibers are applied to a metallic sectional piece having a simple geometric shape, and are then held thereon without restraint by a metallic counterpart piece. Then, the unit consisting of the sectional piece, fibers and counterpart piece undergoes plastic deformation in vacuo between mold halves by applying pressure at an elevated temperature, without bonding of the fibers to one another or to the building component metal. By further increasing the pressure and/or temperature, the molded unit is compressed further between the mold halves and is consolidated to a monolithic part by metallic bonding (diffusion welding), whereby the part, either alone or bonded to other parts, forms the building component, after cooling and removing it from the mold halves.Type: GrantFiled: February 2, 2001Date of Patent: March 2, 2004Assignee: MTU Aero Engines GmbHInventors: Michael Buchberger, Bertram Kopperger, Alexander Sagel, Axel Rossmann
