At a recent auction, I was the top bidder on a piece of metal honeycomb insulation. It's about 6"x6"x4", with dark orange material on one side. There is some red spray paint on most sides, and two holes are drilled/punched in the middle. Finally, a metal tag with a series of numbers has been attached to it.

I'm not going to get my hopes up that it was flown, or if it was it can be identified as such. I'll just be happy if anyone can tell me, by looking at the photos or by the numbers on the tag, anything about it.

Here are some photos:

Here is a close-up of the metal tag. The numbers on it are:

10160-0162-
101
27R1668 0155
BA69VC 31

If anyone knows someone who might be able to look up that number, I'd sure appreciate it if you could let them see this. Thanks very much for your time.

Being honeycomb does not equate to insulation. Many composites are honeycomb and just are structural elements. The red material is RTV.

My take on the red was that it is paint denoting scrapped status and the tan material an unidentified epoxy. I dont think that aluminum (or stainless steel) honeycomb seen in this artifact can be characterized as a "composite" though do agree this is most likely a structural member of sometype

I'm still puzzling over my item three years later, and I just noticed this lot at RR Auction. Does anyone else think it looks like a close match? The RR description doesn't quite clear up exactly what it was used for - absorb the shock of the launch? In what specific area, and for what purpose? Thanks for any opinions.

Honeycomb material in shock-absorber roles is designed to crush with applied load, while being very light-weight, reliable, and without significant rebound. For example the Apollo lunar module and the VIking '75 lander legs used tubecores of aluminum honeycomb as impact force absorbers.

The unit on the RR auction site looks to have absorbed a minor impact of a large circular or cylindrical object pressing into the comb structure. Perhaps a hold-down nut or similar restraint.

The shape of your item and the RR-auction item do have many similarities.
