<div class="section abstract"><div class="htmlview paragraph">Carbon/Carbon brakes in Racing are in use since the 80’s, directly derived from aircraft brake materials.</div><div class="htmlview paragraph">Racing cars evolved so much since then that dedicated materials, design, quality tools, simulation &amp; testing tools have been developed through the years.</div><div class="htmlview paragraph">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.</div><div class="htmlview paragraph">Brembo effort on C/C brake materials will be shown, including:<ul class="list disc"><li class="list-item"><div class="htmlview paragraph">new patented/patent pending fiber architectures to tune desired final mechanical/thermal properties</div></li><li class="list-item"><div class="htmlview paragraph">self-developed CFD and chemical simulation of CVD furnaces to optimize product variability and maximize production efficiency</div></li><li class="list-item"><div class="htmlview paragraph">self-developed non-destructive quality tests to check 100% of actual production</div></li><li class="list-item"><div class="htmlview paragraph">advanced structural and CFD models to achieve efficient extreme cooling patterns</div></li><li class="list-item"><div class="htmlview paragraph">materials that may be tuned to the thermal, mechanical, friction and cost desired final properties</div></li></ul></div><div class="htmlview paragraph">Such know how has been brought into a new generation of high performance C/SiC brake materials, with the scopes of:<ul class="list disc"><li class="list-item"><div class="htmlview paragraph">Achieve high performances typical of Racing brakes</div></li><li class="list-item"><div class="htmlview paragraph">Minimize the weight and rotating masses on a car</div></li><li class="list-item"><div class="htmlview paragraph">Maintain “comfort” behavior as today “ best reference ”</div></li><li class="list-item"><div class="htmlview paragraph">Easy to use out of racing environment too</div></li><li class="list-item"><div class="htmlview paragraph">Maximize rotor life and minimize rotor/pads consumption, for a “greener” usage</div></li></ul></div><div class="htmlview paragraph">A vision for future directions of such material is forecasted</div></div>
