摘要： A foam for use in a lost-foam casting process utilized in the manufacture of a component for a gas turbine engine, the foam having a void fraction less than or equal to ninety five percent, is disclosed. The foam may include a first layer comprising polymer foam having an open-cell structure and a void fraction greater than ninety five percent. A second layer, comprising adhesive, may be adhered to the first layer. A third layer comprising particulate material may be adhered to the second layer.

摘要： A method to manufacture reticulated metal foam via a dual investment solid mold includes pouring molten metal material into a mold while the mold is located on a chill plate. A method to manufacture reticulated metal foam includes pouring molten metal material into a mold while the mold is located on a chill plate, the chill plate configured to apply an externally driven temperature gradient in the mold so that solidification progresses from the chilled end to the non-chilled end
