Re: aircraft flooring
We are using a similar material, scrap that was donated to us by Pratt & Whitney, COTS material made by Hexcel. It is 1 inch thick aluminum honeycomb with 18oz cloth face sheets. The raw material price that they paid was $1100 for a 4 x 7 sheet, which is what I'm using for our cost basis. The largest single component we are using is a 28 x 36 piece which prices out at about $275 - less than the $400 allowable.
I spoke with the engineers at Nida-Core (they are about an hour north of us) and they have a similar material; It is COTS - the core is stocked but laminated sheets are not normally stocked. They have about a 2 week turnaround to laminate it so it's well within the guidelines. They also said they have been bombarded with calls from FIRST teams.

So why are we trying to go to Mars? It's because it's bigger, better, and bolder. Doing what nearly no other team can do, and defying all those who say it can't be done. That reward is a lot more than 9 points. - Mike [more]
