cf doors

not many people make them due to the complexity and the safety issues....
a wreck would be 10x more fatal... even at low speeds.

cf & fiber have the same strength until you get into the range of 7+ layers... which would cost ~3gs a set.
Composites shatter, whereas metal bends.
Do you mean cf (carbon fiber) and fiberglass are the same strength? If so, that's simply not true. They are pretty much the same weight, only less carbon is required to get the same strength as fiberglass.
As far as doors go, I would think that you really don't need any strength in them (as far as structural support goes). Do you wan the cf doors to reduce your weight, or for the look?
td-civ - I see that you're in Brantford, I live in St. George. I'd love to come check out your ride and/or give you a hand working on it. I'm setting up my 92 Civic for autocross next year.
yeah what would i know considering ive only been playin around with it for the past two years and have a cousin who has 6 years of commercial boat building experience 
its a misconception.. yes it is stronger, but 1-3 layers is going to be negligible... same as glass

The only place I've seen those deadly things are on Ebay. I hope you're builing this car for the track or shows only because a cage will not save you in a side impact w/ paper doors. You would just have a roll cage bar where your ribs now reside.
the money invested into unsafe cf doors could be put to much better use.

on subject.....why do you want them?
So down from 7+ layers to 1-3... I agree that any very thin layup won't be strong, regardless if it's carbon, kevlar, or glass. But the fact remains that carbon is stronger. You also have to consider that there are different grades and weaves of carbon (with different thicknesses), each with their own strengths and weaknesses (rigidity, torsional strength, impact resistance, etc).
The company I work for specializes in the design and build of aerospace components using advanced composite materials. I doubt that the carbon you have been "playing around with", or that which is used in boat manufacturing (which is mostly glass from what i understand) is anywhere near the grade of carbon that we use.
Anyways, like everybody says, you don't want carbon doors. Carbon shatters and splinters like glass in your house. You would probably be ok though if you used lots and lots of layers, but then you're talking megabucks. Aluminum would be better.
just think about it.. i wanted them so bad i had them on order ( 6 week wait ) then i thought about it my cars and everyday driver and people just dont know how to drive.. just last night a girl almost ran into me twice and then said it was my fault.. BTW thats why u hear alot of people say it dont have to be your fault..
