This is the forth attempt to send this through......: After receiving an email from an overseas KR driver advising of a different approach to gluing canopies I tried a little test. One sample was with two layers of cloth and Aeropoxy. The second was with one layer glued with cheap polyester resin (Bondo) with peel ply followed (after curing) with a layer of cloth glued with Aeropoxy (to check compatibility). The side with Aeropoxy only is strong but can be peeled with some effort. Mark L?s canopy is attached with this approximate method and has yet to exit the aircraft in flight (a good thing!). The side with polyester glue on the bottom layer to attach to the plastic will not come off short of destruction of the assembly! The second layer, glued with the Aeropoxy, with not come loose from the underlayment except where there was a bubble of separation. My conclusion (please form your own) is that the canopy should be glued to the glass with polyester followed by glass (carbon fiber) glued with your favorite epoxy resin to attach to the canopy frame. The results can be seen in the last picture of my picture log: https://picasaweb.google.com/103552664644911775549/KR2SS# Your results may vary.....that method has not been flight tested.
