Patent ID: 8858846

Claim:
A method for manufacturing a carbon-carbon composite brake disc from a preform, the method comprising densifying the preform to form the carbon-carbon composite brake disc, wherein the preform comprises carbon-containing fibers ranging in length from 1 to 30 mm, a carbon matrix bonding the carbon-containing fibers, wherein the carbon matrix is formed via carbonization of a resin binder, and titanium carbide particles having a particle diameter in the range of from 0.01 to 10 microns, and wherein the densified carbon-carbon composite brake disc exhibits a brake effectiveness μ of less than 0.200, wherein μ = T Average ( p Average - bprt ) ⁢ ( 2 ⁢ N R ) ⁢ A p ⁢ R m where: T Average —Average torque generated by the brake; P Average —Average brake hydraulic fluid pressure; bprt—Brake pressure rotors tight, lowest pressure at which the brake generates torque; 2 N R —Number of friction surfaces (twice the number of rotors N R ); A p —Total hydraulic fluid piston surface area; and R m —Mean brake radius.
