What are aircraft floors made out of, in other words, whats under the carpet? When you walk on it, it feels like either a really hard plastic or rubber. Obviously, there are crossbeams running through the floor, correct?

737 floorboards are of honeycomb composite construction which are screwed down with titanium screws into nutclips or nutplates attached to aluminum floorbeams. Nutclips are just like they sound; they have a nut built in and clip around a hole. Nutplates are similar, but more solidly attached; they are riveted to the supporting structure. Floorboards have foam tape on the underside around the edges where they contact the structure and the ones in the "wet areas" (lavs/galleys) are sealed to prevent corrosion. The carpet is attached with double-sided tape.

The Hexelite Company of Casa Grande AZ is one of the biggest vendors of these floor boards. You can get more info from their website.
I'm not too sure about the titanium screws, though. Aluminum and Titanium don't play very well as evidenced by the 757 Door problems ten to twelve years ago.

Usually honeycomb (Aluminium, CFRP or GFRP). As far as I know, Boeing planes have CFRP more often, whereas Airbus ones tend to have GFRPs - although that memory may be wrong and ultimately, it's up to the airlines.
As 747Skipper said, the area under the lavs is usually metal (urine has ammoniac in it, which is highly corrosive for aluminium! - Does anyone know whether that lesson was learned "the hard way" (i.e. by lots of corrosion & early retirement or even serious incidents)?)

I'll concur with 737 Doctor. Titanium screws in the floorboards, and practically everywhere else in that airplane. I'll also admit to tossing a few titanium rico tips in amongst the Philips heads, just to get a charge out of NKP-S2.

OK I'll admit it. I'm older than most of you. The floor panels I remember were all balsa wood with aluminum skins. I never saw a honeycomb floor board. Logical thoughthat a honeycomb has replaced this as we used to guess the weight of the woman that trashed the panels because of the high heels, sexy as hell but destroys the balsa/aluminum combo quickly.
I am glad I was around to fly before de-regulation.

No, I'm serious, once on a unnamed cargo charter, saw a deck floor patched with plywood. It wasn't too big, maybe 1-2 sq. feet, but it was plywood. Knew it was too cause it didn't flex like the normal flooring does.
is that a light at the end of the tunnel or just a train?
