carbon fiber or titanium?

wich is stronger lighter? i want new shock towers, disk brake and radio tray for my ntc3. wich wold be the lighest/strongest, ti or cf?

Carbon Fiber

Density 0.0654 lb/in³
Tensile Strength, Ultimate 551000 psi
Modulus of Elasticity 33100 ksi

6-4 Grade 5 Titanium

Density 0.16 lb/in³
Tensile Strength, Ultimate 130000 psi
Tensile Strength, Yield 120000 psi

Titanium has a higher tensile strength yield given any cubic inch. Depending on your definition of "strong", titanium is less prone to shearing and can resist stress better.

Be prepared to pay a wack load of money for either of these materials, with Grade 5 titanium usually being more expensive at around $20 a pound.

For shock towers I would give Titanium a try just because most carbon fiber cars have carbon fiber shock towers. The good thing about carbon fibre shock towers is that they tend to bend a little to prevent snapping. But remember, If the titanium shock tower doesn't break, something else will. The weakest will fail first. EG, the shock load will be transfered to something like the diff casing.

For a radio tray I wouldn't use titanium or carbon fibre because radio signals don't permeate through titanium or carbon fibre too well.

Titanium wil make your car havier, Id go with carbon fiber.

I have an RFX which comes with a Carbon fiber radio tray. As long as it's mounted to something plastic first(Servo mounts, reciever case etc) you won't have any problem. For shock tower mounts you may want to find aluminum. It's not quite as strong as titanium but it's much lighter.

titanium is stronger but carbon fiber is lighter. So i am going to let you pick.

What's wrong with plastic:confused: :confused: :confused: :p
