Why would you want to make rotors out of titanium? I know it's thermal conductivity sucks. does it still radiate heat well? with the large temp gradients I would imagine the radiant heat dissipation would suffer.

I would think that the heat capacity and thermal conductivity of titanium would rule it out as a choice for rotors. Our team had a set made in the past that warped very quickly. They were swap-outs for steel rotors of the same size and were just not designed properly. A titanium alloy may be a different story.

we had a set of Ti rotors on our old baja car they ate tha crap out of the pads but they didn't warp because they were thicker than .125. very light though. the car could stop from full speed in 8 ft.

well yeah but for a baja that's only like 15mph.

not quite 15 mph more like 25-28 mph. granted it's not really fsae speeds but still.

I don't know if I'm a dork because I calculated this, an asshole because I'm pointing it out, or probably some combination of the two, but 25mph to 0 in 8 feet is over 2.5G's, 15 to 0 in 8 feet is about 1G. Either way that baja car had very good traction.

Sorry, I had to say it, couldn't help myself.

I once saw RIT's baja car stop in about 5 feet from about 25 mph. But it was because the front tires planted and the rears lifted in the air until the car went perfectly vertical and fell back down. The cg on these things are horrific because most mount the engine high due to lazy packaging. Causes the rear tires to leave the ground and high braking rates sometimes.

There must be SOMETHING to the titanium rotors or a company wouldn't be making them and successful dirt racers wouldn't be using them. They might not be ideal for FSAE, but they have a place somewhere I'm sure. I'm sure Penn State has eyed them or at least tossed the idea around. Did they even use steel for rotors on their car?

Lots of people foolishly use lots of foolish parts and dont complain because almost always anything is better than stock and/or they dont know better.

Eh. People buy Titanium parts/pens/whatever, and spec stuff to be made out of Titanium, just because its cool.

I care most about fab time, since I have to make the stuff. Easy to kick out a steel drive sprocket in under 2 hours. Titanium? Yuck.

That and with steel you can go down to most shops on campus and they'll just give you plate steel for free. Good luck finding .250 or .375 plate 6-4 in a bind.
