Definitions

  • the metal fibers are dispersed to form a felted body of randomly disposed, intersecting metal fibers.
  • the felted body is then sintered, causing the randomly disposed fibers to interdilfuse and bond together at the points where the fibers intersect or touch each other.
  • the body thus formed is substantially uniform in bulk density and porousness, the pores in the body being interconnected and joined and being substantially uniformly distributed throughout the felted, sintered body.
  • fiber metal bodies are of use where very low bulk density, high porosity, is required.
  • the strength of such bodies is normally a disproportionally small percentage of the strength of the solid metal, and application of such bodies is therefore inhibited.
  • the unbonded ends can be bent outward from the mat surface.
  • the nap which results from the bent or outwardly projecting fiber ends is undersirable in many applications, posing an obstacle to smooth air flow over the surface of the sheet, for example.
  • reinforced bodies of metal fibers are formed 'by suspending metal fibers in a fluid suspension medium and forming the fibers into a felted body of randomly disposed fibers.
  • a pervious metal sheet which may be woven, expanded or perforated, is placed over one or both faces of the felted body.
  • the felted body and the sheet, or sheets are then compressed and, while compressed, the' temperature of the felted body and the sheet is raised to the diffusion temperature of the metal, or metals, in the felted body and the sheet.
  • the metal, or metals, of the metal fibers in nited States Patent the felted body and the sheet sinter, forming diffusion bonds between the fibers in the felted body and between the fibers at, or near, the surface of the mat and in contact with the metal sheet.
  • the reinforced body thus formed is a felted mass of randomly disposed, bonded metal fibers reinforced on one or both sides, depending on whether woven, expanded or perforated sheets are employed on one or both faces, by a metal sheet, the sheet, or sheets, being imbedded in the surface of the felted body.
  • One of the objects of the instant invention is to form improved fiber metal bodies.
  • a still further object is to form such bodies whose strentgh is enhanced at low bulk density.
  • FIG. 2 is an exploded view, in perspective, of the fiber metal mat of the instant invention.
  • a metal fiber mat in accordance with U.S. Patent 3,127,668 is formed.
  • Metal fibers are suspended in a fluid medium and felted from the fluid medium into a felted mass of randomly disposed fibers.
  • a woven, expanded or perforated metal sheet or screen is placed over one or both faces of the felted fiber mass. While holding the felted mass and metal sheet together under a light load suflicient to maintain contact between the felted metal fibers with each other and with the metal sheet, the felted mass and metal sheet are sintered together at the appropriate sintering temperature.
  • Both the fibers and the reinforcing sheet may be selected from a wide variety of metals and alloys, depending on the properties desired and the use to which the end article is to be put.
  • the metals and alloys must, of course, be cosinterable.
  • the metal sheet either woven, expanded, or perforated
  • the sheet and body are placed under a light load and compressed
  • the metal sheet is imbedded in the surface and bonded to the fibers on or near the surface of the body.
  • the reinforcing sheet forms a layer at the surface of the reinforced body, bonded to the felted body, which is both continuous and planar.
  • This continuous and planar layer resists stresses which, otherwise, might cause failure at the surface where the felted fibers, although continuously metallic, are random with respect to direction.
  • the continuous layer provided by the metal sheet also decreases the possibility of free fiber ends on the surface.
  • the metal fibers may be felted onto a woven, expanded, or perforated metal sheet and, where such a sheet is to be used on both faces, the metal sheet may be placed on the opposite surface after felting.
  • the fibers may also be felted and positioned on the metal sheet after felting.
  • the sintered m-ats were tested for tensile strength.
  • the unreinforced mat had a tensile strength of 3300 p.s.i. while the mat, reinforced on both sides, had a tensile strength of 4525 psi.
  • a reinforced mat comprising metal fibers randomly disposed in a felted body of intersecting fibers, and said fibers being metal diffusion bonded to each other, and pervious metal sheets on opposite surfaces of said mat, each of said pervious metal sheets being metal diffusion bonded to one surface of said mat and imbedded therein.
  • a reinforced, compressed mat comprising a body of randomly disposed, intersecting metal fibers which are metal diffusion bonded to each other, and pervious metal sheets at opposite surfaces of said mat, said mat being between said pervious metal sheets with said pervious metal sheets imbedded in said opposite surfaces in contact with, and metal diffusion bonded to, said pervious metal sheets.
