Ali Honeycomb get used lots in racing.
I worked for a company called DJ Racecars who buitl their Firecat from Ali Honeycomb panels. There was an article in Car and Car Conversions on it
years ago - 99/00 i think. The photos in it show you prety much how it was built.
Mostly made from flat sheets or some bend with glues/rivitted joints. Used machined alloy bulkheads but the rest was honeycomb.
Without any parts bolted to the chassis you can pick up the tub by one end and hold it. Light stuff.
Car was fitted with a standard hibusa engine and was scarily fast So big all round. Much faster than the equivilent radical of the time.
Theres photos of it on their website www.djracecars.com

yep roy dawson. Quick quick guy
The firehawks are a fair price, but similar money to an equivilent force i think. But then again their carbon composite tubs.
Who ever mentioned Hexel. Good call, took some time to find the right bit of their site, but the bit on honeycomb panels is interesting.

link to pdf
Could anyone please send me a link to the pdf you have been talking about that describes the construction of the honeycomb chassis? Thanks

This discussion is 11 years old, I suspect things have moved on since then

I think you will be lucky. Its an 11 year old conversation and most of the main contributors are not active on here any more.
I would suggest looking through the websites they discuss and see if that brings anything up.
Track days ARE the best thing since sliced bread, until I get a supercharger that is!

Thanks guys for all the replies. Yes the thread is old but the topic still relevant. If someone has the mentioned pdf please send me a link thats all
i want to take a look and maybe run some simulation (eg energy absorption in comparison to a similar spaceframe),study joining methods and bulkhead
using the article as a starting point etc.Thanks again

You might find some of the discussion on these threads interesting, if you haven't come across them already:

I am intending on using such board in an upcoming build of a super high MPG car. Specifically I am going to use Cellite 620:
http://www.trbls.com/wp-content/uploads/2013/03/Cellite-220-620-Panels-March2013.pdf
£272 + VAT per 8'x4' sheet
You can cut and work this material with normal woodworking tools, jigsaw, bandsaw, circular saw, router etc. Or it can be water-jet cut.
I use Areldite 420 high strength structural epoxy to join it, that stuff is mighty strong, I have made several test joints and tested them to
destruction.
Some good articles on building a car with this matirial:
http://www.autospeed.com/cms/article.html?&A=112925
and
http://www.autospeed.com/cms/article.html?&title=Building-an-Ultra-LightWeight-Car-Part-2&A=112926
I am doing things a bit differently, I have decided to delete the side door for example, in order to get a stronger, stiffer chassis.

I design with this in my day job. I don't think it's that hard to use in situations away from my normal work but I'd be wanting to
be very careful. It's stiff and strong but it requires careful loading and load path design as it doesn't cope with peel or point loads
very well. I actually work with trbls on custom parts all the time. I've designed fastener inserts with 5KN+ pull out load but the problem I
have is that failure propagation is often hidden and quiet until it's too late.
I may still use this for chunks of stiffening but I'm not sure I'd make a full chassis from it.

There's a chapter in Tony Pashley's book about such construction. You should be able to have a read here (Contents/Aluminium Honeycomb)

Sad to realise that I have been building my car longer than this thread has been running.
