Attaching to NidaCore
For NidaCore or any sandwich construction, how you attach to it will depend on what you want to attach and the thickness of the core where you are attaching. Assuming you're going to use something like a 1" NidaCore, you can:
- Laminate from the NidaCore to the object, good for bulkheads/partitions, extend your fiberglass tape couple inches from either side of joint, number of layers dependent on stresses. Same way you'll join the walls to the roof, etc.
- Rivet through into the core, good for small hardware. This assumes you've put up enough 'glass on the surface to hold a rivet, but you wouldn't have to do this everywhere, just where you're dropping the fasteners. Better in shear than stress loads.
- Bonding direct to the surface, using any of the typical construction adhesives. Good for large surface area parts where the load is distributed
- Through bolting, good for heavily stressed hardware. Good practice is to use a hole saw to drill out core, then refill with a solid laminate, then drill through that so when the fastener is compressed the core doesn't yield.
Most of your questions I'm answering based on boat construction techniques, so you can always search on the web down that line and get much more detailed information.
Hope this helps
