Carbon Overlying

[GT-5732]

I found this on another forum and thought it was good, so im sharing.

Here's a guide on how to carbon overlay parts of your car.

You will need the following parts -

Carbon cloth (twil looks best)

resin

acetone (if u want to clean your brushes - i use cheap ones and bin them)

plenty of latex gloves

mixing pots

measuring jug

syringe (for measuring hardner)

masking tape

Sharp scissors

Some stirrers - I use wooded spatulars

emery cloth

wet n dry 400grit to 1200 grit

polish

1) measure up your carbon cloth for the piece to be covered. Then using the masking tape tape up both sides where you intend to cut the cloth to prevent pulling the weave then cut through the middle of the tape -

2) Prep your piece to be overlayed - it should be black, if its not spray it up first so a colour doesnt show through the weave. It also needs a rub down with emery cloth.

3) brush a thin layer of resin mixed with 1% harder over the part to be overlayed then press the carbon cloth gently into place and tape up to the rear of the part to pull it into shape. You may need to change your gloves often so you dont pull the weave. Leave to dry for approx 45mins

4) Start building up thing layers of resin, you will need approx 5 layers to prevent breaking through to the cloth when sanding down. Each additional layer should be added after around 7 mins when the previous layer turns to a jelly consistency. You will now need to leave it for 1 week to fully cure -

5) you will now need to trim the excess cloth off - best tool I found was a dremmel -

BEFORE:

AFTER TRIMMING:

6) Start sanding down. work your way from 400 grit up to 1200 grit wet and dry then finish with a good quality polish for a really nice shine -

Great Find Adam

I will definitely give this a go

Great find

Where do you get carbon weave from and how much does it cost roughly?

Most fiberglassing places sell it

[Basti]

im guessing this will be a lot harder than it looks. for me anyway. great post though

[Craved]

good walk through - thanks for sharing.

just be sure to take into account the additional material thickness for fitment when replacing the parts.

[GT-5732]

Yeah thanks guys.

Im not sure on cost for all the materials. You should be able to get the carbon cloth from most custom fibreglasses.

I think it would be Harder then it looks but i think it can be done but u need to take ur time in doing it.

how would you go about doing dry carbon finish :S ?

Dry carbon uses a completely different production method and shouldn't be confused with wet-lay up.

I will assume you mean a raw finish which is most commonly associated with 'dry carbon' which can be achieved by just leaving the carbon with the resin and not adding a clear coat.

yeh just a matte finish without the gloss

um not sure how mine is gonna turn out, my cf stitching is comptletely drifferent compared 2 ur's.

im practicing on sum pieces of wood 2morro. lol

how did u get the material 2 stick in2 the grooves? im guessing glue maybe.

my stitch's are just like lil squares side by side. ie. ooooooooooo

ooooooooooo

ooooooooooo.

i'll post a pic up 2morro. that'll b easier. lol

[Craved]

yeah pics will be easier - but the twill pictured in the first post is all held in place by the resin .. no need for glue.

Sounds like you have Plain Weave Carbon Fibre. The stitch is woven in a checker pattern.

The carbon used in the pictures is 3k 2x2 Twill weave (most common carbon fibre found)

how go is the carbon fiber and risen in hight heat condition

[Craved]

how go is the carbon fiber and risen in hight heat condition

define high heat, then an answer can be provided

look into auto-claving - used with vacuum mnolds and pre-preg carbon fibre - AKA how a ferrari is built. you cant do that at home, but it will tell you the curing temps.

also - you can powdercoat fibreglass if its done correctly - so it can handle 230 deg C atleast

i was thinking of carbon fiber over laying my timing cover and igniion cover.

so it should work?

[omy-33]

it's easy 2 cure, when u have big ovens, lol

the ovens at work are set to 120degrees. so my practise pieces cured in say half an hour to an hour

[bloodsword27]

good find, will be doing my front bar soon. wat brand of resin+hardner u use and whered u get it from?cheers

[omy-33]

any good fibreglass place, i think i even saw resin an hardener at autobarn.

[Neil]

Nah bugger autobarn,,,any good boat shop sells it.

No carbon fibre but heaps of fibreglass stuff.

I found this place at Warwick farm,,,I went out to have a fag at lone star and they were next door and they have lots of shops.
