Source, cost?
I expect that the plates are bonded with the rivets only used to hold them tightly in place.
Will be a nuisance to paint.
Unsure of service life.

maybe it is possible to make a chassis with it?

A chassis like this one, you mean? :

wo~ do u have more information of it?

Not a lot, but what do you want to know?

It was a prototype presented last year by the UK company Westfield - a collaborative project between them and AIE (who produce a lightweight Wankel engine) and Axon (who produce the carbon fibre tubes).

The photos and information sheet were from the launch presentation at last year's Niche Vehicle Networks symposium - a UK organisation formed to support and promote the UK's specialist car/vehicle industry, of which I am a member.

I suspect that it was more an exercise to extract the government funding that NVN offers for such projects, rather than a serious production prototype - I made inquiries about purchasing the AIE engine for one of my projects, and the price is ludicrous and completely uncommercial. It has gone very quiet since they presented it.

The chassis was designed with steel front and rear subframes on a carbon tube/sheet central tub, so that Westfield's various engine/suspension package options can be easily bolted on to a common centre section.

A couple more photos:

oh, can I find it on Westfield website? I tried but didn't see it

No they're keeping very quiet about it - other than the presentation at the NVN Seminar (which is a requirement of the funding agreement), I've not seen them promote it anywhere. Draw what conclusions you will from that.

I have to say that it didn't look very sexy - as you can see from the photos, the joints looked downright amateurish.

but in another site, it looks like have a full carbon version

I'll use rivet joint if I really make this

I'd suggest bond and rivet: rivets will fret and become loose very quickly if they're used as the primary connection in carbon fibre. Use a bonded primary joint, with rivets to prevent peel.

That's a previous prototype they did for Caterham. Rumour has it that it never ran, was not developed, and was later stripped for parts.

This is a picture of the bare chassis for that car:

do there any reason y they stop that?
