Abstract: In a method for at least partly metalizing the surface of a laminated component, the layer of material which is to form part of the surface of the component is first metalized; then it is coated, as are the other layers of non-metalized material, with a polymerizable resin; and lastly the coated layers are stacked on the lower part of a mould, which is then subjected to pressure, possibly under heat.

Abstract: A flexible, electrically conductive jointing material consists of an elastomer containing metal in a divided state distributed in its mass. The metal is in the form of laminae or paillettes of aluminium or of aluminium alloy, the length of which is greater than their width or thickness. The elastomer, which may be the product known under the name "Thiokol", exhibits a pasty consistency when applied enabling it to be spread with a spatula and mixed in situ. The jointing material may be used for connecting together the structural parts of aircraft.

Abstract: A method of preparing an antistatic coating exhibiting a desired value of surface resistivity which is substantially stable with respect to time takes as its starting point a commercial antistatic product having a synthetic resin base and substantially free from metallic particles but of which the surface resistivity, measured after mixing with its hardener and drying, is very much below the desired value. A compatible insulating resin is added to this product so as to raise the surface resistivity, still measured after mixing with the hardener and drying, to a value much higher than the desired value. The resulting product is then subjected to an accelerated ageing treatment causing a reduction in surface resistivity with terminal asymptotic development to the level of the desired value. Such a coating may be applied to radomes and other aircraft surface elements, and has the advantage that its conductivity does not increase appreciably with age.
