ABSTRACT:
A porous metallic material of the present invention is constructed of a laminate consisting of an expanded metal and a fibrous metallic fiber both of which are pressed to be joined to each other under pressure. This porous metallic material is excellent in bending strength and workability. The porous metallic materials may be laminated to a honeycomb structural element and a rigid plate so as to form a porous structural material. To this porous metallic material may be also laminated a decorative layer so as to form a porous decorative sound absorbing material. The present invention provides the above-mentioned products and method for manufacturing the same.
