Group: Forum Members Posts: 36, Visits: 118	Hi all, I am making sandwich panel and i am looking at making the carbon skins first and then sticking each layer to either side of a nomes honeycomb core material. I have thought of four options here > 1. make the outer skins, key the back of them paint brush resin on to the skins and stick either side of the honeycomb, then vacuum 2. make the outer skins, key the back of them soak the honeycomb in resin and stick either side of the honeycomb, then vacuum 3. make the outer skins, key the back of them adda 400g pre-preg layer to the back of the skins and stick to the core, vacuum, oven… 4. same as options 1 & 2 but instead of using resin use a film adhesive, question is where can i get this from, is there different weights of adhesive if so which is most suitable and where do i get it from?? hope you can help, Lee.

Hi Lee I have done some honeycomb work as you described in step 1 and 2. But I don't think you will get the strength of bond with just brushing epoxy resin onto the honeycomb mating surfaces. The resin (in my opinion ) is too thin. What I did was to add cabisol to thicken the resin till it was as thick as epoxy adhesive. I brushed it on the carbon sheet and using a fine nap roller carefully applied the mixture to the honeycomb. I prefit the parts and then peel it apart to see if it imprints everywhere. I then re assemble put release film over the open cells and then breather and vacuum bagged at a low vacuum. Hope this helps. Fred
