Abstract
A method for fabricating a metal foam component from an aerogel containing a polymer and nanoparticles is disclosed. The method may comprise: 1) exposing the aerogel to a reducing condition at an elevated temperature for a reaction time to provide a metal foam; and 2) using the metal foam to fabricate the metal foam component. At least one of the elevated temperature and the reaction time may be selected so that at least some ligaments of the metal foam have a desired ligament diameter or at least some pores of the metal foam have a desired pore size. The desired ligament diameter may be less than about one micron and the component may be a component of a gas turbine engine.
