Abstract

A composite material including a first porous metal body having a three-dimensional mesh-like skeleton, a second porous metal body having a three-dimensional mesh-like skeleton, and a bonding portion formed by entanglement of the skeleton of the first porous metal body and the skeleton of the second porous metal body. The porosity of the first porous metal body may be different from the porosity of the second porous metal body.

Claims

exact text as granted — not AI-modified

1 . A composite material comprising:
 a first porous metal body having a three-dimensional mesh-like skeleton;   a second porous metal body having a three-dimensional mesh-like skeleton; and   a bonding portion formed by entanglement of the skeleton of the first porous metal body and the skeleton of the second porous metal body.   
     
     
         2 . The composite material according to  claim 1 , wherein the porosity of the first porous metal body is different from the porosity of the second porous metal body. 
     
     
         3 . The composite material according to  claim 1 , wherein the first porous metal body contains a metal different from a metal contained in the second porous metal body. 
     
     
         4 . A method for producing a composite material, in which a first porous metal body having a three-dimensional mesh-like skeleton is bonded to a second porous metal body having a three-dimensional mesh-like skeleton, the method comprising the steps of:
 preparing a first porous metal precursor of the first porous metal body and a second porous metal precursor of the second porous metal body in a first step;   arranging the first porous metal precursor and the second porous metal precursor such that the first porous metal precursor and the second porous metal precursor at least overlap one another in a second step; and   pressing an overlap portion between the first porous metal precursor and the second porous metal precursor in a third step.
