EPOXY Honeycomb Vs fiberglass

Yes you're right solid provides the most bashablity for the lack of a better word.Easy to repair just not the lightest.

I infused a bunch of layers of glass to around 4mm thick ,comes in at around 700g a sq/ft . Problem was its too small to get any kind of stiffness testing done.Tough as nails though so need to make some bigger samples.

 

SukiSolo,

I agree you don't have to use the identical material. The whole point here is that you have to decide how important light weight is. Then you choose your material for lots of different legitimate reasons.
But if light weight is not worth a lot of money, don't do core.

No one should care about aviation, except as an example of known extreme usage of technology. Oracle is the only place where I know it is worthwhile (America's cup)

Tungsten,

Since it is too small for a test, do a different one. First measure the volume, then the weight and calculate a density. Then cut into the sandwich. look at how much air volume is left in the core. It's been known for cores to be completely filled with resin, negating the best value for core.
