To provide a method of forming a metal foam filled composite member in which the composite member is formed by combining the metal foam and a structure member, it can be simply integrated with the structure member and strength required as the structure member can be stably ensured.
In the method of forming the metal foam composite member, the composite member is formed by combining the molded metal foam 5 and a cylindrical thin-walled extrusion 4. Cylinder walls 2d, 2d are deformed such that a cross section in a direction perpendicular to a cylinder axis direction of the extrusion 4 gets smaller than the cross section of the metal foam 5, and the metal foam 5 is pressed-in the extrusion 4 in resistant to the deformed cylinder walls 2d, 2d. The metal foam 5 is fixed into the extrusion 4 utilizing restoration force of the cylinder walls 2d, 2d.
