Does anyone here have any experience of working with honeycomb sandwich panels. Looking to build a box body for a 4x4 and being considering the options.
The material looks like the right product so keen to understand the benefits and pitfalls of working with it from the experience of others(use of the hive mind), and what is/isn't possible?

I fitted out a Luton van as a mobile shop - the rear body including floor was made of that honeycomb stuff, what do you need to know?
Previous owners had secured to what appeared to be rivet nuts in the material and they were spinning happily so had to be cut off flush and left, bolting through it for fixings outside you need big spreader plates and I used spring washers and nyloc nuts.
I fixed a lot to stuff internally with a tiger seal equivalent, it's travelled a fair bit since it was done and nothing has moved.

Curious about the challenges for joining seams/corners, was assuming bonding then an external support over the joints, much like the old Marshall BFA bodies(so expensive these days, but if I'm going to spend money it might as well be custom to my needs.)

Honeycomb? Hive Mind? Would you bee using buzz words to make puns and jokes? Well I hope someone pollinates your mind with a rich nectar of inspiration, but short of waggling my fingers and having a bumble on google I'm afraid my brood of expertise is rather thin, so I shall just leave you with the sting of a pointless post.
(Nonesense aside, what material are you looking at? Aluminium? Wood? Plastic?)

Looking at aluminium honeycomb and options around aluminium or composite face. My thought process is around not using timber to construct the frame as part of weight management

Interesting! Aluminium can be a bit of a pain, it likes to clog blades up. I'd imagine honeycomb has the additional nightmare of the internal structure, though in truth I really haven't used it before so I would be really interested to follow your build!

Ah I thought you were talking about the plastic honeycomb stuff. Basically that slots into mouldings you can buy to cover most eventualities, looks to be bonded/ sealed in with a tiger seal type adhesive. Where doors hatches etc are fitted they have trimmed round the outside edge with another moulding and bolted with coach bolts.

I think this stuff generally always uses extruded aluminium corner/edge sections doesn't it, regardless of material?
I can't think of any application I've seen it used it where it doesn't anyways.

It's used extensively on some older aircraft (the Gazelle in particular, which is nearly all honeycomb fuselage). Bond in inserts for securing things (we use microballon and an araldite but tiger seal etc would be okay on a truck) rather than bolting through and trying to load spread,
Cap all edges with alloy angle or it will get destroyed in seconds.
Honeycomb is light and strong but it's a very thin outer skin, so it doesn't like sharp point impacts - so don't use it where you're likely to pierce it.
