Saturated aircraft brake preform including coal tar pitch and preparation thereof

A method of making a saturated aircraft brake preform placing a carbon fiber preform; under a vacuum heating the carbon fiber preform; introducing coal tar pitch having a softening point in the range of about 160°C-240°C into the carbon fiber preform; pressurizing the coal tar pitch saturated carbon...
