Foamed Aluminum

[gpapag]

Any ideas on when composites became commonplace/usable?

Andrew, see the section ‘History’
Honeycomb structure - Wikipedia, the free encyclopedia

I have seen honeycomb panels in McDonnell Douglas F-4 Phantom and in civilian Boeing 707-1xx (both coming from mid 1950)
European firms Dornier and Fokker had introduced honeycomb panels in their aircrafts ~15 years prior to these.


Some tech data regarding the Aluminum Foam panels

This isn't honeycomb it's foam and looks like a sponge but very stiff.

Can I have a sample? I'm interested in making a face plate from the 1 inch thick open cell foam.
At 6% aluminum, that 19 x 15.75 inch sheet would weigh 1.8 lb. Is that right?

The 1/2" is expanded about 5 times for 19% of the volume is aluminum.

The 1" is about 6% volume is aluminum.

I'm going to post some applications and PDF data over the week.

So the 1", being about a third as dense, actually weights less (for the same area) as the 1/2". Interesting...

Thanks for that info - as I said, I have more questions about this stuff, I just don't know what they are!

I'm still looking forward to those applications and data!

You have PM.

I know what to do with it...

Can you tell? Post pics? Something???

Oh, I'm sorry. I didn't think anyone here was interested. I have attached a 1/8" thick soft elastic layer to the 1/2" for a turntable shelf. It's on ebay. The problem is that no one has yet to see and touch it and both the elastic layer and foamed alu is very expensive but still cheaper than most other damping or isolation shelves or panels.

Hello
am also very interessted in some data

... I'm going to post some applications and PDF data over the week.

Can you share at all how you made it?

I remembered this thread when I read this article - it's a rather vague description of metallic foam, followed by two scathing comments.
