Default Alumalite Splitter/Undertray?

I'm looking for some materials for make an undertray (maybe splitter too), and i can't find a good local abs supplier, but there are tons of suppliers for these alumalite stuff.

Anyone played with this alumalite stuff before?

Laminators Inc. - Sign Panel Products: Alumalite Corrugated plastic core, double-sided aluminum for stability and strength

It's two thin aluminum sheets sandwiching a plastic matrix. I remember playing with a bar of aluminum/cardboard composite in college, and it's surprisingly stiff for it's weight. I wonder if this is the same kind of composite, but I can't find any engineering specs anywhere.

Locally, it's $85 for 1/4" 4'x8'.

I don't know if I would use it as is for a splitter, but it does make a perfect material to use as a core for a carbon one. Cut it to shape, seal the edges, lay some fabric and vaccum bag that ****. That's my plan anyway. not a bad price, but I've seen it slightly cheeper.

and why did you post this in the engine performance section?

'lay some fabric and vacuum bag that ****' = $200-300 in carbon, peel-ply, cotton weave, vacuum bag, chromate tape, resin, blahblahblahblah.

I was thinking undertray = better cooling efficiency, so i put it here.

that's not a bad idea, to use it as a core, and lay on some stiffer outer plates.

Sav I hear what you're sayin. my point was though, that by itself the stuff isn't rigid enough. I have some signs made from it, and you can easily fold it in half. But if you so desired to make a carbon or fiberglass splitter, it would make a perfect core material. much better than say balsa or something. and to keep cost down you could always do a wet layup. as for using it as undertray material. . . I think it might work pretty well as long as you can insulate the edges from exhaust heat. Maybe with some aluminium duct tape.

people in the know use carbon or plastic for splitters because if metal goes under the car, it takes other stuff with it.

Hustler if you are in Houston, Austin, SA (Plastic Supply of San Antonio is where I get mine), Dallas, even Shiner (Boedeker plastics) you should be able to find a local plastics supplier no problem. That way if you need a big sheet you do not get killed on shipping.

Cool...right now I've abandoned the splitter idea and I want to just seal up the rad and make a belly pan so I can get the car on the track this year...its been 2-years since the last event. Besides, I'll need the top fuel wing before the splitter.
