Since I will be attaching my canopy soon I thought a test was in order. I gouged (very rough) an area in some bead foam and roughed up (very rough!) a piece of left over canopy material. Flox was applied to the foam, the canopy material applied to the flox (no glass)and carbon fiber was applied to the outside of the canopy material. Please note that the foam was so rough there was not 100% contact with the canopy plastic. The carbon was not completely wetted out. I purposely set up a scenario of failure to see how well the joint would hold when not even done properly. The results are the three last pictures on my photo site. After 24 hours and an insufficient cure I really had to struggle to break loose a corner. The carbon fiber separated from the epoxy (Aeropoxy) but the epoxy could not be removed from the canopy plastic! After a full cure of the epoxy I can honestly say that, if installed properly, the canopy is not going to separate in flight! The bond is unbelievable strong! The key is to roughen the plastic to the point that the epoxy has something to hold to, just like Mark L. said!
