Drilling Carbon Fiber
�
�
So... Is it possible to drill holes in a carbon fiber hood with a standard drill/bit or do I need to exercise some "special" technique or purchase some "special" equipment? I'm assuming its rather similar to fiberglass which I'm used to working with. Thanks in advance.

Yep, just go nice and slow, and try to avoid cracking it.

Tape it with masking tape A BUNCH over the area you're drilling before you start... and drill through the tape...

yes, that would be a good idea.
Just do it SLOOOWWWLLYY

Just wonder'n if there is a thread about the benefits of CF...i mean..its cracks so easily..isn't it supposed to be super duper strong or something? other than the bling and the weight factor.....what else is it good fer, oh, and i read on mr2oc.com that it has like a 85% better heat exchange that aluminum for an intercooler :D...

REAL carbon fiber hoods.... yes...
Cheap Fiberglass overlay CF hoods... NO...
Real ones are SUPER light, and durable. The ones that most people put on their cars are just cheaper made ones, meant only for looks...

What's VIS carbon fiber? It's the good stuff right?
| aznatama | 08-22-2004 01:34 PM |
no, VIS is overlay. overlay is basically a fiberglass hood with one single layer of cf laid over it for looks.
a REAL 100% cf parts are made in an autoclave, which is a giant oven. mich like how the McLaren F1 chassis was made, 100% cf parts like the ones used in F1 cars are made by first conforming the resin impregnated cf to a mold, and then vacuum bagging it and baking it in an oven at high temperatures (~200-300deg F I think), and high pressure. the result is a superstrong piece that is also super light and superstiff. you can basically make a useable hood that is a single layer as long as it's reinforced along the edged where it mounts to the hinges.
with a real cf hood, a WRX version would weigh about 5lbs. the top secret supra hood weighs like 9 lbs... but the supra hood is like twice the size of our hoods.
the bad part is that a hood like this would cost ~800.

my buddys fiberimages hood for his integra is entirely CF. when in the sun, you can see through the CF weave when the hoods up!
| aznatama | 08-23-2004 05:16 AM |
lawn boy, your buddy's hood is an example of a autoclave / dry carbon hood. it's plenty strong with a single layer. I'll bet it's pretty light too huh?
anyways, a composite pc is only as smooth as its mold, and only as perfectly replicated as the skill of person laying the cf onto the mold =)

I used to have a vis hood on my car that the previous owner bought... the hoodscoop ripped off. Dont buy that crap.

everyone is saying slow.
I would say very high speed, virtually no pressure.
definetly tape.

best thing to use is a DREMEL :D
| DocWRX | 08-23-2004 08:49 PM |
Good, sharp drill bits. Old, nasty, dull, nicked ones will pull the fiber and tend to tear it more than cut. And moderate speed/moderate pressure is better than too fast. Too slow will tempt you to put too much pressure down - if you need much pressure, your bits are too dull.

Yup... same way on the fiber images hood I have on my wagon.

Assuming that most people would use a power drill / cordless drill without adjustable rpm, I thought "slow" in previous posts meant slow advance rate of the drill bit towards the workpiece, not slow drill rpm. Which is somewhat similar to your "virtually no pressure" approach.

crack? unpossible! carbon fiber is hard to damage.
| Wolfen42 | 08-24-2004 02:06 PM |
I had no problems drilling through my hood. Just put a bunch of masking tape around the whole area to catch any bits of melted stuff that might happen if you have your drill running at too high a speed or are using a dremel...
| Ravenous | 08-24-2004 07:27 PM |
did a carbon fiber hood install today, used the dremel again.It works at a high rate of speed not pulling,but creating a nice round area for hood pins.Plus there is no force being applied to the hood when using a dremel

Along with the masking tape.....

Use a few layers of masking tape on the front AND the back of the area you're drilling into, AND put a scrap piece of 2X4 (or any other type of wood) directly behind the carbon. All of this helps keep the carbon fiber from splintering. Go nice and slow, and believe it or not, you can use a little water for a cooling agent while drilling, if you need to, depending on how THICK the carbon is in the area you're drilling.
I have a lot of experience with this sort of thing.....(15 years and counting as a structural repair technician in the USAF).
Good luck :cool:

if your going to drill holes the absolute best way to do this is buy yes taping first.. but whear most people go wrong with working with any type of carbon or kevlar is when trying to do so they just find the size bit that they need and comense to drilling...... this is WRONG... the one ond only way to drill into your hood.is to get atleast 3 brill bits the one that is going to result in the hole size that you wish to end up with and 2 smaller.... start with the smallest bit to drill a pilot hole this helps prevent drill bit slide and cracking and makes your job easier...
switch to the next bit and continue the process. this is whear you want to use a moderate speed... and little to no pressure the pilot hole will do all the work for you ...
final bit. this should be the easiest.. you should not have to worry about any cracking but you do need the speed of the bit to be rather fast to make the final hole clean and neat.....
this is the only process that will give you worry free results ......

so..did you drill through this mystery carbon fiber?
