摘要： Method of making a carbon-carbon composite article such as an aircraft brake disc. The method includes: selecting carbon fiber precursors, having limited shrinkage in the axial direction when carbonized, in the form of individualized chopped or cut fibers; placing the selected chopped or cut carbon fiber precursors into a preform mold configured in the form of a brake disc to form a fibrous matrix; and then needling the molded fibrous matrix to provide it with three-dimensional structural integrity and to reduce layering. The carbon fiber precursor matrix may subsequently be infused with liquid carbon matrix precursor, the impregnated matrix may be carbonized; e.g., at 600-1800° C. for 1-10 hours to provide a preform having a density of at least about 1.1 g/cc, and the carbonized preform may be further densified to a density of at least about 1.6 g/cc by known liquid resin infiltration techniques and/or by conventional CVI/CVD processing.

摘要： Constraint fixture for processing annular preforms. The constraint fixture is made up of a lower plate, a top plate, a ring for the outside diameter of an annular preform being treated within the constraint fixture, and a ring for the inside diameter of the annular preform. The outside diameter and inside diameter rings are made of thin flexible sheet metal strips or thin flexible carbon-carbon composite strip material. The thin flexible strips are joined together by deformable joints, so that the flexible constraint system retains pitch within the fibrous matrix of the preform. The outside diameter strips may be joined together by expandable joints and the inside diameter strips may be joined together by collapsible joints. Also, a method of avoiding damage to an annular fibrous preform, e.g., an aircraft brake disc preform, during a carbonization procedure. This method involves carbonizing the annular fibrous preform in the constraint fixture of the invention.

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 resin transfer molding (RTM) apparatus (10) that includes: an extruder (4); at least two mold cavities (15) contained within a mold (16, 18) in the apparatus, arranged so that resin can be extruded from the extruder (4) into the mold; a nozzle (20) for delivering resin from the extruder (4) into the mold; runners (25) in the body of the mold to deliver resin from the nozzle (20) to a mold cavity (15) within the mold; a venting area (29) contiguous to each mold cavity to permit gases to escape from the mold cavity (15) when the mold cavity is infiltrated with resin; and a press (12) to force the mold (16, 18) closed during at least resin injection. An advantageous feature of the present invention is that the mold may be configured to accept a part (19) that is characterized by variations in length, width, and/or thickness, such as a wheel beam key. Also, an RTM process. The process includes: placing a porous preform, e.g., a wheel beam key preform, that is characterized by variations in length, width, and/or thickness into a mold held in a press; injecting a molten resin or pitch into the mold, wherein an extruder is used for injecting the resin; allowing the resin to cool below the melting point; and removing the impregnated preform from the mold. This process is especially adapted for processing fibrous preforms, carbon fiber preforms, nonwoven preforms, random fiber preforms with binder, and foam preforms.

摘要： Methods of making a carbon-carbon composite preforms, particularly suitable as brake discs in aircraft landing systems, by combining titanium carbide particles ranging in size from 0.01 to 10 microns in diameter, resinous binder, and carbon fibers or carbon fiber precursors in a mold, and subsequently subjecting the combined components to pressure and heat to carbonize the resinous binder by methods, thereby providing the carbon-carbon composite preform having particulate titanium carbide uniformly distributed throughout its mass. Prior to combining the titanium carbide and the binder with the fibers in this process, the particulate titanium carbide may be mixed with liquid binder, the resulting TiC/binder mixture may then solidified, and the resulting solid TiC/binder mixture may be ground into a fine powder for use in the process. Also, compositions for preparing a carbon-carbon composite friction materials, and methods of improving wear and dynamic stability in a carbon-carbon composite brake discs.
