Definitions

  • the present invention relates to laser marking and specifically, but not exclusively, concerns laser marking of aircraft cables.
  • the electrical cables used in aircraft are high quality cables in which an electrical conductor is covered by a polymeric insulating layer, such as that sold under the trade mark KAPTON, and an outer layer for permitting marking of the cable.
  • the outer layer may take different forms eg. a tape of PTFE or ETFE wound on the cable, a dispersion containing PTFE or FEP in which the cable is dipped or an extrusion.
  • the current method of cable marking is hot stamp printing. This method has the disadvantage that it degrades the thermally insulating properties of the cable which can cause arc tracking.
  • infra-red lasers for cable marking.
  • One proposal involves coating cables in a proprietary coloured emulsion which changes colour when irradiated by a CO2 laser.
  • Another proposal is to include an extra outer layer on a cable which is coloured differently from the underlying layer and using an infra-red laser and a mark or laser scanning arrangement to remove parts of the extra layer to achieve the desired marking.
  • cable comprising an electrical conductor surrounded by a polymeric insulating layer containing a photosensitive substance permitting marking of the cable by an intensive source of ultra-violet or visible radiation.
  • a cable according to the present invention may comprise only a single insulating layer thus enabling weight and cost savings in comparison with known high quality cables such as those used on aircraft.
  • the photosensitive substance may be titanium dioxide, which is presently used as a pigment or filler.
  • the insulating layer contains between up to 20% by weight of the photosensitive substance and preferably up to 5% by weight. It is thought that around 4% by weight may be the chosen amount.
  • an article to be marked will be made so that the amount of the photosensitive substance in a surface layer of the article is enhanced relative to the remainder of the article.
  • the insulating layer may be made from polyimide and specifically may be made of the material sold under the trade mark KAPTON.
  • titanium dioxide it is thought that alternatives to titanium dioxide are possible and that, for example, zinc dioxide or tin dioxide may be suitable photosensitive substances for use in a cable according to the present invention.
  • a method of marking a cable such as an electrical cable using an intensive source of ultra-violet or visible radiation.
  • a laser source is used although a very intense UV flashlamp may be an alternative.
  • the method comprises irradiating the cable with an excimer laser, eg. a krypton fluoride (KrF) laser.
  • an excimer laser eg. a krypton fluoride (KrF) laser.
  • KrF krypton fluoride
  • a mask may be used to define the required marking.
  • aspects of the present invention are applicable to articles other than electrical cables for aircraft.
  • the invention may be applicable to fibre optic cables or to tubes housing such cables and to a variety of articles other than cables
