Definitions

  • Foam structures are known in industry and the number of applications for metallic foam structures is continually increasing.
  • aluminium foam metal having a continuously connected, open celled (reticulated) geometry is available and employed in:-
  • the high surface to volume ratio allows for a compact design and the high specific stiffness, that is, high strength to weight ratio makes the material useful in aerospace and car applications.
  • Foam structures are now proposed for high pressure gas containers and in particular high pressure gas containers having an irregular shape for example a non-cylindrical or spherical shape.
  • foam material such as metal foams are formed typically by mixing small quantities of a gasifier e.g. titanium hydride with aluminium powder and subjecting the mixture to heat and pressure to form a sintered sheet.
  • the sintered sheet or a portion thereof is then placed in a mould which is then heated to higher temperature at which the metal melts and hydrogen is released from the titanium hydride to provide an even dispersion of bubbles.
  • a fluid extraction tube is cast into the container and the moulded object is then allowed to solidify and subsequently shock quenched in a cryogen, for example, liquid nitrogen.
  • the extraction tube normally penetrates far enough into the metal foam container to provide a mechanically firm anchor but fluid access to it is limited by the diameter by the extraction tube.
  • a gas container made from metal foam includes at least one extraction tube a portion of which extends into the container said portion being formed with a plurality of perforations or slots.
  • a plurality of perforated extraction tubes are provided each being connected to a common manifold.
  • a gas container 2 made from metal foam includes an extraction tube 4.
  • the extraction tube 4 is cast deeply into the container 2 and the portion of the tube, where it is cast within the container 2 includes a plurality of perforations 6.
  • the function of the extraction tube 4 with the perforations 6 is to collect and convey gas from all parts of the container 2 and thereby enable extraction of the gas to take place at a fast rate.
  • the gas container 2 may be provided with two or more extraction tubes each of which is connected to a common manifold.
