Dear All

Can you clarify how to bond / laminate a sandwich panel from cured flat sheets of carbon fibre using Nomex honeycomb as the core please? Your Nomex honeycomb pages say to use epoxy resin. The aluminium honeycomb recommends a Permabond structural adhesive. Would I be better to use the structural adhesive for Nomex?

Would your recommendation change if I were to use one of your foam core materials.

Thanks in advance.

Regards,

John

I've found that when bonding the second "skin" onto the nomex honeycomb on curved parts, i make up a hand lay-up second skin, and let that cure to a kind of "soft tack" (Since i need to drape it on the curved honeycomb)  I "prep" the honeycomb by "dabbing" on laminating resin on to it, using a small sponge...

This means that I need only one mould (for the outside of the sandwich) but it also means that the inside skin will be a bit heavier and have a higher resin content.

I tried to infuse a flat piece, and de-bag it before it was fully cured ... what a mess ...
