[NSRCA-discussion] composite plates?

[Richard Lewis]

You can also mix Microballons/cabosil with polyruethane glues to makes a non-sagging polyurethane glue.  I've used this in a few places with success.....your mileage may vary...

In my CF Aeroslave Aries fuse, I glued all the honycomb parts in with unmixed white super-fast 5-minute gorilla glue.....the PU glue expands and fills the open cells in the honeycomb.  Worked well so far, but the Aeroslave fuse interior is cormat and fiberglasss that bonds really well with most adhesives.  I also often use gorilla glue and then follow with CA in few places to tack parts in places while the polyurethane glues cures and expands.

I have started to use some stuff called "Plastic Weld" made by Devcon/Permatex. Glues air to water!! Thicker two part glue that is amazing stuff. Comes in a syringe applicator, Just squeeze out what you want and mix. About a 5 to 10 minute working window, sets fast and sands really nicely too. Great for fiberglass repair too. No idea why they call it "Plastic weld" but it is great stuff.

3,500 psi bond, water proof, everything proof
