As most of you probably know i was building a full body kit for a Tj. I have since changed my mind and decided that for the moment i will just be building the front bar and to complement the swanky looking front i will be doing a new bonnet highly likely from carbon fibre with evo7style centre vents.I will be doing an exact copy of the original to use as a plug before the actual mould that il be doin for the evo7 design so this will allow me to make other moulds of different designs easily that could possibly be resold with whichever design you desire in carbon fibre,Fibreglass or whatever you want that i could mould onto. Are there any people who would b interested in buying a relatively cheap new bonnet of your choice jsut so that i no how many i might be able to sell because after this project im gonna b kinda scrounging around for cash and anything would help!
Cheers,

my honest oppinion carbon fibre look on a FWD non import doesnt work ,,,

i was looking into an evo style bonnet that came in carbon fibre... but i was planning on painting over it...and despite what ppl may say it does not defeat the purpose, cos CF is not meants to make an interesting look on the bonnet it is meant to be lightweight and dosnt heat up as easy...... u can get carbon firbre look alike contact for the look lol :P ... i say paint over the CB ...

also it would suck to put money into developing ur bonnet only to get defected for it ....... or even worse be involved in a head on crash and get decapitated cos it hasnt been engineered properly :P

good luck though, good to see ppl extending out the square of what a modded magna is

shame your not doing one for a tl, I would be interested, I would have it painted, but the vents, oh the vents.

My point was that im doing mine carbon fibre but im leaving a mould so that i can do more of them in whatever design somebody wants so if you want just a regular fibreglass bonnet then that can be done.But im painting my car black in the near future and i thought i might aswell get some experience with carbon fibre aswell and i will do better in my HSC because of the different types of materials and yada yada...And also since this is a pretty indepth project it will meet all legal requirements for strength and i will be using only pan based fibres.

Oh by the way here is a 5min chop job of what mines going to look like.

i really dont think it would work too well on a TJ hood, with the smaller raised section in the middle. would probably be more suited to smaller vents either side

You have my support. I have wanted something like that for my awd for a long time. :thumbsup:

make a bonnet so u can have a v mounted inter cooler :D

now that would be kool haha .. allu would need is turbo then :(

nah good luck with it though!

And either way, it would look like rice. I'd be colour coding it to the colour of the car or it's going to look like every other black bonnet you see that just happens to be painted matt black and looks like crap.

A dude in the US has or had bonnets available to suit TE-TH's. Problem is they are too strong enough and are a danger to others in the event of an accident. They need to be designed to adhere to crash standards.

gimme a sec and ill try find a pic of the NS.com project car that was in a head on with CB bonnet ... makes u think twice about it !

there ya go .... look how much impact was on the front of the car yet the CB bonnet did not crumble with the car, if the hinges broke i dare say they would have been headless

Mate honestly thats ugly. Though if you do make up carbon fiber bonnets I may consider one that looks like a factory bonnet and paint it. Should save a few kilos. Whats going to be the cost of this anyhow?

The thing with carbon fibre is that when under extreme strain it will also flex like steel but it has a high ultimate tensile strength and elastic limit which allows it to simple well pretty mch absorb the force and then just return to its normal shape.If you want to see something interesting do a little bit of research on carbon nano-tubes.This little things are used to make a product with a strength value that is 267x stronger then steel and weighs as much as regular carbon fibre!!!

And yeh that photo does look a bit ugly since i did it so fast but it was just to give a quick idea.With mine im not actually doing to have the large hump bit in the middle but more to the sides a bit with the vents in the gap.Iv always thought the evo7 vents looked sexy so i thought hey why not and if it doesnt look how i want i can always go sell it on ebay!:D As for the price i havnt purchased any of the carbon fibre yet but if i no that i could sell maybe 5-10 of them i could buy it bulk which would make it a lot cheaper, and also if you just want a straight copy or if you want something new done to it. But my best guess at this moment would be $400-800 depending, but i will be looking more into getting the materials so il be able to give a more accurate price soon.

I'd doubt that would be desirable in an accident. Regular bonnets aren't designed to absorb the energy then spring back. That could be a very bad thing.

I'd buy one but only if it looked very nice and classy not too much rice and i'd paint it white the match the car :)

As for the crashing? well i hope to never crash but if it happens, hell lots of people with skylines ect have CF bonnets and i've never heard any bad stories!

Yep i'll have one
:D

how are you going to make it, i remember reading about carbon bonnets make sure you give it a weak spot (in the middle somewhere), carbon being as strong as it is if you are in an accident it can be pushed the bonnet into the cabin rather than bending like a normal bonnet.

but i wouldn't mind one,

would look cool if the bit on the TJ bonnet was raised up a little more with some sort of vents on it.

Sorry but that's kinda wrong. The actual carbon fibres are flexible and are quite like most fibres (cotton, string, etc) in the amount of flexibility. You are right though about the tensile strength, for those that don't know what that means, is that it takes a helluva lotta force to break a strand if it is being pulled from each end. The reason why most automotive carbon fibre products don't have much flex is due to the polymer used. What your carbon fibre bonnets actually are, are a fibre reinforced polmer. It is the properties of the polymer that mostly determine if what will happen in a collision, all that the fibres will do is hold the structure together.

Just out of interest though what type of process would you use, wet or dry?

I will be doing it wet because i really dont have the equipment to do a dry 1 for something this size and that would also make it more costly because i would have to buy more equipment and stuff so yeh just using wet. And along with this wet process it also gives it a slightly different wavy kinda look which i think is cool makes it more unique, the wet process also gives it slight airbubbles which will slightly reduce the strength of the final product which in turn covers the question somebody else i noticed asked. But together with that im putting the vents in mine just so that it looks good and if i do crash it will sort of crumple and crack rather then juest spear through my windscreen and cut my head off!!!But also the slight lip towards the centre of the stock hook is there for the same kind of reason which will also apply to the carbon hood.

sounds wicked :thumbsup: my mate made a cf airbox wet and it looks sahweeeeeet :D Can't wait to see

Yeh it has a good look to it doesnt it!!:D And if you do it dry then it requires strong vacuums and airtight packaging and to do that for something this size is just impractical

I'll second that, blue magna with a black carbon fibre bonnet, should look very nice

Heres a mates magna with vents in the bonnet.

I'm making a CF one for a TL. already have the Female mould. It's easy. The bonet will not be baked, can't find an oven big enough. BUt it's easy. I'll eep ya posted. Probably 2 months away or so.

cool this is sounding better everyday, i'm definately interested is there an estimated final cost? will you be making many? thanks..

anyone here ever though about having an air inlet on the bonnet at the front on the passengers side ? Direct CAI for a pod ... would be so good heheh, it would look like a charger a little lol

Anyways, keep us all posted !


later:cool:

My uncle worked on a TAFE solar car entry and he helped make the carbon fibre shell. apparently they made the oven for it themselves using house insulation (pink batts etc.) and then had a few sensors connected to a couple of oven elements to heat it up. Apparently it worked pretty damn well.

I would be interested.

white and black look hot

Recently hit a kangaroo in my Magna, so it's given me an
Excuse to upgrade my hood. I'd like to go CF, so how much
were you thinking of charging?

2006.

Oops.

my hood. Thinking of going CF. how much would you charge for that?

hayden VRX was thinking of getting one, but the bonnet is part of a car's crumple zone and will in a crash go towards the driver and it will cost over 2000

my advice, probably get a roo bar or something

Might aswell just post here even though thread is old. Had a few pricings for carbon look hoods, A cashy job from a good mate was going to cost about $1200 for a carbon Wrapped hood (still legal but still heavy)

A pure carbon/fglass mix hood made from a mould would cost between 1000-1500 but is illegal and not much weight reduction, then the 3rd option is Full Carbon which will cost about $2000+, Is illegal but is very light and JDM YO.

The reason they are all so expensive(even the wrap) is the TJ bonnet is very hard to get right, also you will see a line where the wrap is joined in the centre as there are no carbon wrap rolls wide enough to cover the entire thing.
Would be easier with a TE-TH Bonnet.

... my advice, probably get a roo bar or something

That won't help since his front end already hit a roo..

well for his next magna or his current one

either way a bar may be better than getting a Illegal bar as hayden said

this.
I have a piece wide enough to do a TH bonnet at home waiting for a rainy day (sunny day actually would be better lol)
but it only just makes it and the weave will have to curve with the bonnet (imagine unrolling it sideways, its curved at the front of the bonnet and windscreen base)

Pretty sure the pre preg(pre impregnated with resin) carbon fibre rolls we used to use at Qantas were wide enough. I'll measure a roll of Kevlar and satin weave glass cloth at work tomorrow because the rolls are similar in width. Oh, and those who think carbon is okay in a crash......it doesn't handle sudden impacts too well, it kind of shatters and/or splinters making it much more dangerous if you hit anyone like a pedestrian because it can become razor sharp.

And also because a standard steel/aluminum bonnet actually absorbs a shit load of energy as it crumples. Carbon fibre doesnt.

Very true.

Carbon fiber doesn't crumple. It just shatters. Could cause some serious injury and your ctp insurer won't cover you for damages. Even in a front ender you would be screwed.

Well done for repeating my comment almost to the tee haha

Forgot to post the dimensions. The rolls of kevlar and glass we work with are 1300mm wide so the carbon was probably the same. Okay for my RX3's bonnet, no good to do one piece on a magna.
