Abstract
A system is disclosed comprising a carbon/carbon brake disk comprising a carbon fiber having a crystal orientation (CO) between 80% and 100% and a coefficient of friction of more than 0.183 in response to a rejected takeoff condition.
Claims1
A method of improving rejected takeoff (RTO) performance comprising:
- providing a first densified preform manufactured using a first manufacturing process, the first manufacturing process being free of a fiber crystal orientation (CO) improvement process;
- providing a second densified preform manufactured using a second manufacturing process, the second manufacturing process being the same as the first manufacturing process except the second manufacturing process includes the fiber crystal orientation (CO) improvement process;
- wherein a second coefficient of friction in the RTO condition of the second densified preform is greater than a first coefficient of friction in an RTO condition of the first densified preform.
