Brake Systems and Composite Rotors: How Racing Can be a Vision for High Performance Cars

Carbon/Carbon brakes in Racing are in use since the 80?s, directly derived from aircraft brake materials.

Racing cars evolved so much since then that dedicated materials, design, quality tools, simulation & testing tools have been developed through the years.

Today a Racing car brake is no longer just a brake but it?s a very integrated system in the vehicle aerodynamics, a way to control tyre temperature and to optimize BBW system strategy in order to improve overall performance.

Brembo effort on C/C brake materials will be shown, including:

new patented/patent pending fiber architectures to tune desired final mechanical/thermal properties

self-developed CFD and chemical simulation of CVD furnaces to optimize product variability and maximize production efficiency

self-developed non-destructive quality tests to check 100% of actual production

advanced structural and CFD models to achieve efficient extreme cooling patterns

materials that may be tuned to the thermal, mechanical, friction and cost desired final properties

Such know how has been brought into a new generation of high performance C/SiC brake materials, with the scopes of:

Achieve high performances typical of Racing brakes

Minimize the weight and rotating masses on a car

Maintain ?comfort? behavior as today ? best reference ?

Easy to use out of racing environment too

Maximize rotor life and minimize rotor/pads consumption, for a ?greener? usage

A vision for future directions of such material is forecasted
