Yes mate, can make it look a lot neater, here is a redtop heatshield we have recently done with a rolled edge, .7mm thick made from a 3 layer stack
The main thing to notice is the edge, most composite makers will simply make an oversize sheet then cut it back to the correct size, doorcards is a good example. We try to use a rolled edge where ever possible, it means a fair bit more work but the end product just looks better.
Hope this makes sense.
p.s. come on kjimbo get your saph up to autoflock hq!!! promise I will do you a nice brew

towards the weekend really ideally Saturday as thats pretty much a chill out day for us so all the major work is done, could nip to the local caff for a spot of bruch whilst the mould is curing 
Got a bit of pressure on at the mo finishing a carbon front splitter, carbon 106 bonnet, carbon corsa b bonnet and tailgate, carbon evo 6 bonnet for trl just to name a few :-(

sounds like a plan Jimbo mate, have think of any other little carbon bits like this as they are brill for making good use of off cuts due their size, I bloody hate throwing fabric away (which I dont, started stuffing pillows with it now)

its a neat way of doing it.
You will still have a cut edge its just hidden out of sight and smooth with the back of the part.
You using high temp pre-pregs for exhaust heat shields?? or just a high temp resin made wet?? some of the high temp pre-pregs are very nice just very expensive!

we dont use pre-pregs, no need to as they are far too over engineered for most automotive applications and the equipment required would outweigh the income, not to mention its hard to get a good finish straight out the mould with pre-preg. (high temp autoclave)
The parts are not cured at room temp but are elevated and the moulds are post cured.
On our bonnets we dont use latches what so ever, the only part which is metal is the tapped insert for the hinge, and this is actually cnc's out of aviation grade billet.
In regards to other details about release agent etc that a close kept secret im afraid as its the prep of the mould and the resin systems used which play the biggest factor into the parts finish

Hello Rslubby, price would depend on what resin system is required, I would estimate something around £35.00 £45.00 but would need to confirm this, you see its not just the resin which has to withstand the high temps but the laqcuer too, but we have yet to have any issues with laqcuer failing, the resin is the important one to get right

well mold prep an release agents go hand in glove as you can have a smoothest polished mold and use a release agent that can mark the product and wether its a chemical release or pva is used a mold will need a release agent and surely a resin system is fo ar the aplication I.E wet lay or wet lay bagged or infusion !
Cheers Andy + we are not traders on here due to cut throat trading so our prices arnt relevent

Mmm Carbon...
Any interest in making an exhaust heatshield for the Fiesta ST? In a similar way to the vauxhall engine previously pictured...
With most tubular exhausts the old heatshield cannot be used and engine bay temps are markedly warmer.
Could have kit car applications do depending on design, and the Duratec is quite common...!

@ Wolves - if there is demand then there will be a product, you know where we are so if you want to help us develop a product for the ST we would be more than happy
@ Brettski - no worries, once Jim has popped up and ive got the mould done we can get one made and heat test it with some different resins, once all the materials are decided then the price will be confirmed but I can't see it being that much as the main factor is the resin as the fabric can consist of offcuts. Did the faci arrive for you mate?

There are a fair few carbon parts available that are popular for the Fiesta ST from Streamline but the quality is a little questionable from the bits I have seen - mirror caps in particular were a dreadful fit
Some decent mirror caps and a good quality replacement exhaust heatshield for use with aftermarket manifolds would be a good start, and there are few other under-bonnet bits that would be nice if available...

bang on the money there jay,
for a high temp pre-preg bonnet you are looking around 10 - 15K!!!! but you have to factor in the machinery required to do something this sort of size and the mould itself would cost not far off that as well, in some cases they are simply machined from billets then bolded together.
Also the time plays a big part of it, if you notice tyhe mould we use for the small heatshields for the red top, we can produce 4 at a time which means there is minimum waste and time is spent much mroe efficiantly.
But when we do carbon zetec covers we can only do them one at a time due to the depth of the edges, on an infusion process it more effective to make one at a time and do not finishing than top make a multiple part mould which would need more time finishing once the part has been proken out (if that makes sense)
But there is so much gash out on the market its unreal but people seem happy to pay stupid money for them.
We are currently doing some composite panels for a tuning company, we visited their premises and spotted these panels which they had already purchased from a competitor, one panel weighs 800grams and is supposidly carbon fibre. Aftser some discussion we are now remanufacturing them PROPERY, I will post up a little thread in the pictures forum once we have completed the first panel to let everyone know how to tell proper carbon and good qualitty from imitation/cheap composites. As a guide though to replicate wht they had just purchased we could of produced each panel for around £20, they paid £170 plus vat TRADE!
