Celica Forums General Discussion Exterior regarding carbon fiber hood...

a friend of mine is strongly anti-carbon fiber hood ... ~ his reason's tat when you crash (touch wood), the carbon fiber hood (cuz it's carbon fiber) cannot absorb the reaction force (unlike factory hood) and it will fly RIGHT INTO the interior and chop ur head off (or wherever) ~

p.s: he's no into much of the looks things but ... tat's not important in this case

a demo picture of his theory:

No, the carbon fiber hood would break a lot easier than the OEM metal hoods, meaning that if anything, pieces of carbon fiber would go everywhere, but hey, it's better than glass.

Besides, in a crash, hoods don't fly off, they bend and crinkle, and if a hood were to fly like that, since it is held on by hinges in the back, it would likely fly over your car, and not cut you in half.

This is total BS, don't listen to your friend...

First off, Carbon Fiber hoods are made for racing applications, I.E. they're designed with safety in mind.

Carbon fiber is strong stuff, and, just like Fiberglass, if enough force is acing upon it, it will shatter. Force of impact will flex the carbon fiber hood. (like a bow or a fishing rod), when it reaches it's limits fo flexure, it shatters into many pieces. this shattering action is what absorbs the force of an impact. This is why they can make cars like the corvette, which have 100% Fiberglass bodywork.

The key is installation, the parts must be installed correctly so they bend and fracture like they're supposed to. Properly aligned, and properly torqued fasteners on hinges and latches
are a part of this.

Now, there is a possibility of the hood doing what your friend said, but there have to be some important conditions present for this to happen.

1) your setup doesn't have hood pins: if the front corners of the hood are not secure, the hood latch may break away and the hood flies up, and less force is absorbed. For safety, and to keep it street legal, you MUST have hood pins in place.

2) the winshield is gone; the windshield is stronger than that Carbon Fiber hood, so, it should'nt penetrate it. Also, if the hood is torqued down properly, it should stay connected to the firewall.

Maybe on a kevlar piece, I'd worry about that happening, since it's much tougher than carbon. Carbon Fiber and Fiberglass hoods are safe, so long as they're installed correctly and secured with hood pins.

It's more like the drawing below:

Besides, if you're in an accident powerful enough for you hood to do that, then you are probably dead anyways, at least before the hood hits you.

thx thx thx ~

u see ... there's always people who make rumours base on their knowledges and spread them ... then there's people who pass them ...
for me ... i'd like to make sure with people i can trust better ... altho internet dun sound like the right place ... i believe in majority ... and all these car fans on the forum with experience and knowledge ~

you're friend is just trying to scare you so you don't have a nicer car than him.

lol agree agree ~ when i get my veilside GT ... hehehe better not be to SHOWY tho ... dun want my car scratches

Off topic, I am LOVING the diagrams!

nice drawings. as said before don't listen to your friend
it's

yeah he knows that the celica is the sexiest

haha...good drawings...no that is BS...i dont even own a car and i know that crap is wrong...buy a Carbon Fiber hood and drive to your friends house to piss your him off

you guys are hilarious!!

the drawings should be stickied for future references concerning the safety of Carbon Fiber Hoods !!!

awsome pictures

yea, in all likelyhood, the hood will most likely shatter on impact...give ur friend a rip, he's just jealous

haha love the drawings

Damn Rave669 I love you're drawing.. incredible you a true artist man no joke good explanation..

Yep, Carbon Fiber is britle...meaning it will crack into pieces.

Oh ya, which head was ur friend talking about? The first picture looks like the hoods going in his groin.

Actually, I went to college for commercial design, four years of it. I usually spend more time on my artwork, but considering I spent all of 15 seconds in paint shop pro throwing that one toghether... Let's just say it gets the pint across

I know it's kinda off-topic, but if you guys want, I can scan some of my automotive/celica-related sketches and post them in a new thread. (I also created the artwork for my sig, BTW)

Love your avitar. She's thinking... "hmmm this trophy smells like LAST years winner." LOL it looks like a huge dick!

OMG!

old post risen from the dead

this is still listed in my favorite threads?

a hood won't make a difference between life and death...
