摘要： Method of carbonizing pitch-infiltrated fibrous annular preform by: infiltrating the preform with pitch; placing the pitch-infiltrated preform in a constraint fixture having an ejector base plate, an inner wall, an outer wall, and a top press plate; selecting the relative sizes of the preform and the constraint fixture so that a layer of inert friable material may be situated between the preform and walls of the constraint fixture; placing inert friable material (e.g., activated carbon) between the preform and the top, bottom, and walls of the constraint fixture; and subjecting the pitch-infiltrated fibrous preform to carbonization in the constraint fixture. The activated carbon or other inert friable material adsorbs pitch molecules that escape the preform during carbonization, which reduces problems with foaming. The layer of activated carbon or other friable material between the fibrous preform and the constraint fixture also provides an easily crushable region that facilitates removal of the preform from the constraint fixture after carbonization.

摘要： A pitch densification process which is widely applicable in the densification of carbon fiber preforms and stabilized pitch fiber preforms. The process includes: (a.) introducing liquid pitch into a fibrous carbon preform; (b.) carbonizing the pitch-impregnated preform by heating it in the absence of oxidizing agents; and subsequently (c.) further densifying the carbonized pitch-impregnated preform. The pitch used for densification may be coal tar pitch, petroleum pitch, or synthetic pitch. The softening point of the pitch will normally range from 100° C. to 340° C., depending upon the properties to be imparted to the finished product.

摘要： Method of manufacturing carbon-carbon composite brake disc comprising a dense reusable core. Preferably, the reusable core has a density of 1.8-2.05 g/cc. The method includes: forming a dense carbon-carbon composite core; positioning the dense core in a location within a carbon-carbon composite brake disc; and fixing the dense carbon-carbon composite core in place in its location within the carbon-carbon composite brake disc. It is economically advantageous to recover the dense core from a worn brake disc prior to positioning it in the brake disc. Also, an annular carbon-carbon composite brake disc made up of a friction surface containing 15-75 weight-% carbon-containing fibers and 25-85 weight-% resin binder and a dense carbon-carbon composite core comprising 40-75 weight-% carbon-containing fibers and 25-60 weight-% resin binder.

摘要： Process of manufacturing carbon-carbon composite preform by: (i.) arranging batch of carbon fiber preforms in infiltration vessel; (ii.) flooding vessel with hot liquid phase pitch at atmospheric pressure in inert atmosphere; (iii.) raising pressure in infiltration vessel to elevated pressure, and then slowly lowering pressure; and (iv.) repeating step (iii.). An apparatus that may be used is a heated infiltration vessel capable of operating at pressures above 100 psi, possible equipped with means to circulate heated pitch inside the vessel, in order to facilitate heat transfer into the carbon fiber preforms being infiltrated by the pitch. The need for a vacuum pump is eliminated, and the time spent heating the preform is substantially reduced. Instead of vacuum, cycled high pressure is employed to infiltrate carbon fiber preforms with pitch. The use of preheated pitch as a heat transfer agent avoids the slow transfer of heat into the preform prior to infiltration.
