How do I make a strong bond.
Here's the deal...
I need to create a strong bond between a piece of plywood and a piece of nylon.
The design of the piece means that I will constantly be trying to pull the two pieces apart. Unfortunately, this is not avoidable.
Basically this is a modified control horn (half the size of a 1/2a control horn) on the inside of a landing gear door. when the door is closed, the force will be pulling on the bond directly. I want there to be some force on this bond to positively close the door. Also, there will be considerable force when the gear closes the door.
I've tried epoxy, which failed after about 10 closings of the door. CA does not stick to nylon for any length of time.
Screws will not work, as the door is thin and the nylon piece is too small.
What other options do I have?

CF - carbon fiber
have you tried coming thru the door with the horn, this way the flange from the horn would become structural, by being a wider surface to pull on.
or if room allows, perhaps a lite ply cap slid pver the horn and epoxied into place making a much larger glue area.

Your going to have to do a mechanical type assembly. Nylons and polypros are impervious to chemicals along with alot others. Put the horn in the location you want, then reinforce around it. IE epoxies, resin, etc.

Why not make the horn out of plywood? If you glue it on properly it won't come off. A little chopped glass at the base of the joint won't hurt either.

rough it all up and make a fillet all around the base of the horn with balsa dust(i get my balsa dust off my belt sander) soak in thin cyano and stand back until the cyano smoke has cleared. after it has cooled down it should be very very strong.
by the way, balsa dust and thin cyano is good for fillets, especially wood to wood joints where extra strength is needed.
just watch that smoke, it is very nasty if you breathe it in(dont ask me how i know!)
