Looking at ordering some CF cloth to muck around and try make some parts for my car. Been doing quite a bit googling but dont have any solid answers. Anyone have any references (sites/pics/etc) for the difference between 1K, 3K, 6K, 12K etc as to how they look in real life. What is better, twill or plain, which K rating etc. A price guide - where to buy in aus or order from o/seas. In a nutshell, looking for a CF-101 sort of site.

Any of you guys tried doing some DIY parts ? Prefered method of injecting resin ? Pics ?

Thanks !

Have done this myself. It depends on what you're wrapping or making as to what twill and things you need, as some are better suited to straights where-as some are better suited to going around curves. The k-rating refers to the number of filaments in the cloth, so 3k will have 3000 filaments, 6k will have 6000 filaments etc. The lower the number the smaller the weave will be and the lighter and more expensive the cloth will be. You will most likely want 2x2 twill 3k cloth, that is the most common choice for cosmetic applications. 6k will be ok as well. Get 3k if you can. This is what they look like:

Compared to plain:

Can't find any good pictures of 12k weave, but you don't want it trust me. The weaves are huge. 3k looks the best.

As for price, keep in mind that carbon fibre is expensive to make and is therefore expensive to buy. Expect to pay around $80 a meter. If the price seems too good to be true then it probably is. Just search for carbon fibre fabric/cloth on google and there's quite a few stores that come up that sell good stuff. I bought mine locally in Perth for $75 a meter + GST. For the resin, make sure you get a good epoxy resin. If you're doing engine parts, the resin needs to be able to handle the heat. Do NOT, whatever you do, get polyester resin.

That's pretty much all there is to it. I will say from my own experiences... It's not easy. In fact it's really damn hard. Start with something small and simple. Be really really careful with the carbon fabric because it's so fragile and easy to damage before you put the resin on it. Once you apply the resin it's as strong as anything, but you can really mess up the pattern and finish if you're not careful. If you're making your own fully carbon parts instead of simply skinning existing parts, you will need to get some peel-ply to absorb the excess resin otherwise the final product will be really heavy and not very good. You will also need to vacuum bag it while it dries so that it bonds properly.

Good luck eh :)

Ive done more them my share of carbon, kevlar and fiberglass work

The cost is much less if you know where to look , if all goes well in the future i might put together some kits and group buys from my supply source i asked for group buy pricing but havent heard back yet ( friday am )

I can get just about everything you can imagine and some you cant haha

I have just about every weave and thickness in carbon a bunch of kelvar bulletproof stuff in yellow and carbon/ kevlar in blue or red or yellow ( not coloured fiberglass but kevlar unlike others!)

And arramid fiber used in heat shields on jets or turbos

And various resins

You dont need vacuum bags in most cases or even ovens except on wet cool days !!!

Cosmetic parts can be light still

Of course if your after lightweight and super strong the process gets way more expensive and consumes a lot of time to do it right !

Most people just want the looks first

The side afffect is its strong and lighter then fiberglass and can be 7 times stronger then steel

You cant use the cheap resin( fiberglass type) from bunnings on carbon lol

Epoxy is the go and a few other types i get from usa

i have the 12k weave for undertray full length on my car , 1 layer will be strong enough with kevlar scrape points on nose and on impact parts on the new body kit

I have some quarter turn flush quick release like aircraft cowls use coming as well to do some nice toys on my car and yet retain easy access to work on it

    • Yeah well per the video it took 15s for the stock unit to start up....even if I give it a few seconds discount for starting that is at least 12 sec before you get a reverse camera if you are trying to leave a park.  The android unit is way faster, but 2016 for the stock unit is a long time ago in consumer electronics
    • Yea that’s why I said ima test them with multimeter and see the reads.
    • Only at idle. Isn’t a problem when rev it seems.
    • @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?  
    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
