Claims16
A hermetically sealed and structurally joined split aircraft instrument housing assembly made of at least two parts having abutting edges, said assembly comprising:
- two adjacent chamber subassemblies forming an abutting joint of their edges;
- a metallic foil strip of predetermined thickness;
- and
- an acrylic transfer adhesive strip of predetermined thickness adhesively affixed to one side of said metallic foil strip thereby forming a tearband;
- said tearband being adhesively attached, through said acrylic transfer adhesive, to each of said subassemblies about said abutting joint whereby said split housing assembly is assembled and substantially hermetically sealed and structurally joined.
A method for the hermetic sealing of a split aircraft instrument housing assembly, made of at least two parts with abutting edges, said method comprising:
- assembling said parts to form said assembly with a joint at said abutting edges;
- and
- placing a strip of metallic foil-backed with an acrylic transfer adhesive, about said joint so as to also adhesively affix said acrylic transfer adhesive to said parts on all sides of said joint whereby said housing assembly is substantially hermetically sealed and structurally joined.
A split aircraft instrument housing assembly having a foil-backed acrylic transfer adhesive tearband for the hermetic sealing and structural joining of said split aircraft instrument housing assembly, said assembly having juxtaposed abutting edges, said tearband comprising:
- a metallic foil strip;
- an acrylic transfer adhesive layer adhesively affixed on one side to said foil layer;
- and
- a protective peelable layer temporarily affixed to the other side of said acrylic transfer adhesive layer, thereby forming said tearband so that when said protective layer is removed and said tearband is adhesively affixed to said abutting edges, said assembly is substantially hermetically sealed and structurally joined.
