ABSTRACT:
The invention provides a method for producing a microcellular foam of a curable material by replicating a dissolvable particle preform and leaching away the dissolvable particle preform to yield the microcellular foam. The foam can be a preceramic polymer microcellular foam which can be pyrolyzed to form a ceramic microcellular foam. A method for making a composite including steps of producing a ceramic microcellular foam which is subsequently infiltrated to form the composite is also provided as are microcellular foams, ceramic microcellular foams and composites prepared according to the method of the invention.
