Carbon Roof
Looking at getting a Carbon Roof for my Mk2 Fiesta, i know i a few people on here have one, was just woundering how they fit once the old roof has been cut off, do you have to seal it to stop water getting in? what do you use?
Cheers Brian

We used a 3M structual adhesive rather than a bonding adhesive on the MP4 12C, cant remember the name of it off hand but will try and find out, as its structual it'll make it stronger than it would have ever been!! not cheap thou mind u lol. Its used to bond things like the window surrounds etc to the carbon tub, comes out an orange colour.
The bonding adhesive is stonger than tigerseal etc aswell and used 2 bond the non structual parts like the wings, side panels etc, also made by 3M.

yea thats my point, people are saying to use tigerseal or sikaflex etc but their not structual adhesives their just bonding adhesives!!
Would do the job but in a crash chances are the carbon skin would/could come off, so a structual adhesive would be more beneficial and safe, IMO obviously!
Even the bonding adhesive were using on the new mclaren is a shit load stronger than tigerseal etc as their all 2 part adhesives unlike sikaflex etc, but obviously cost alot more!

thing is your removing a main structure panel so unless your car has a tagged cage or at least a 6 point you are drasticly reducing the shell strengh plus i wouldnt use a normal wet lay skin what ever it would need to be a multilay epoxy vacuum infused at least but better would a alloy coned pre preg
the one's iv seen done you only remove the top skin of the roof not the under structure ,so bonding the carbon on top will be a lot stronger than thin tin?

no as the tin as you put it will be stronger ! and it will be worse when done to older cars as they will have even less structural strength in the surrounding shell like cars after 94 as impact laws were tightened , what you have to remember carbon is just like a toughened plastic and will shatter under stress or impact metal might bend but it will stay in one piece

you'll find that the panels that are usually bonded on now are ok because the main shell/monocoque is alot stronger so the cars dont rely as much on the exterior panels for structual strength.
intreagued by the comment bout carbon being like plastic etc and will shatter, obviously piss thin moulds of carbon are likely to shatter but if made properly why would it be weaker than metal?! Carbon done properly is stronger a lighter than metal, which is why the SLR, the new mp4 12c and various other companys cars have a carbonfire monoque chasis rather than metal...... obviously cost comes into it which is why the new car isnt having carbon panels like the SLR did.
Prime example, an SLR was on a road test and pulled out on a roundabout, he didnt see a micra and the micra crashed into the side of it sending it spinning and it hit the door then the quarter of the SLR. The plastic bumper and sidepanel were obviously fucked but the door and quarter panel other than obvious paint damage were actually fine!!!! Had it been a metal car it would have probably written the car off or at least needed a new door and quarter panel.
All comes down to how the carbon is made and what adhesive is used 2 bond it
agree thou slapping a carbon roof panel on an old car like that could cause structual problems if not done properly

Too many posts.. I need a life!!
i wrap cars for a living and if you want to use the carbon wrap vinyl, ill do it for you,
will look fantastic, but bear in mind it will still be a type of sticker,

I have just purchased one for my 106, quite expensive i was Ł1300 all in but that included the roof internal bars aswell, very very nice, bonnet next but thats even deerer at 1500 with 3 door vents, its on the list! mine is the costly prepeg option, im sure carbon roofs require a proper cage.

I read somewhere that making a carbon fibre roof as strong as the standard one would be the same weight or more, due to the amount of layers it would have. So, unless you've got a fully welded in structural cage, you woun't be able to gain any weight loss from the roof anyways...seems a bit of a waste of money to me, replacing a perfectly fine roof, with one that weighs the same, but looks a bit different lol.

and i fail to see how carbon will be the same weight as a steel roof- carbon is far stronger than steel like for like.

As long as the roof is fitted properly, I can't see it being an issue. A bolt-in cage should be more than adequate anyway. There are probably ways of fitting reinforcements to it without adding too much weight if people are bothered.
And, yes, of course a carbon roof will save weight...

As Jay said carbon can be very brittle, which was my point about it needing to be thick enough to have the strength you would need, which would make it heavier heavier than the skin removed!!! it would need to not shatter in a crash and offer structual strength which a thin carbon plate wouldnt do!! but as said you could obviously add a cage or weld a brace across like they have in the link of the M3 csl skin being fitted!!
