With the current world asking for lower displacement high MPG cars for normies, how long will it be until we start to see stuff like pressurized air valve springs into production cars and outside F1 and Moto GP?
We are starting to see the effects of downforce into sports cars, which is an effect discovered and exploited in the mid 80's. And little after that the air valve springs started happening, and little after that the carbon fiber brake discs.
Although considering the carbon fiber brake discs, it wouldn't surprise me if their use is limited to track days and never onto daily drivers.
carbon brakes are noisy and have to heat up to be useful, not very good for the everyday street car.
Jonathan Perez
Bullshit, pal.
Carbon fiber doesn't has to heat up to increase friction. The issue is that the resin heats up too much and the carbon fiber itself goes to shit after 300ºC, Which is MUCH below the temperature of normal reusable steel discs.
Chase Gray
brakes operate best at a certain temperature, carbon ceramics dissipate the heat too quickly for road use.
Jaxon Cooper
>resin Idiot they use a ceramic matrix not resin and they are stable to almost 1400ºC
Caleb Miller
That's not how carbon fiber is made, user. Its a mix between matrix AND resin. If one of them fails, the other one does the same.
Basic physics of brakes, user. The faster you dissipate heat the better. That's the entire point of a brake.
Ian Bennett
it's not carbon fiber, it's carbon ceramic
Blake Lee
Oh, my mistake then. What's the difference in properties and basic making of carbon ceramic vs carbon fiber?
also >For the second step, five different procedures are used to fill the ceramic matrix in between the fibres of the preform: 1.Deposition out of a gas mixture 2.Pyrolysis of a pre-ceramic polymer 3.Chemical reaction of elements 4.Sintering at a relatively low temperature in the range 1000–1200 °C 5.Electrophoretic deposition of a ceramic powder
