Dissimilar aircraft brake systems for use in, for example, an aircraft are provided herein. In this regard, a system is provided comprising a carbon/carbon ('C/C') rotor disk adjacent to a ceramic matrix composite ('CMC') stator disk. In various embodiments, a system is provided comprising a CMC rotor disk adjacent to a C/C stator disk.

Systems and methods for alternating material brake disk stack

The present invention is a composite material, a process and a product formed by the process. The composite is formed by a process that includes forming a fibrous structure comprising fibers into a preform, coating the fibers of the fibrous structure preform with elemental carbon to impregnate that preform, infiltrating the preform with boron carbide to form an impregnated green body. The impregnated green body is infiltrated with liquid naphthalene or other carbon precursor, which is thereafter pyrolyzed to form a carbon char. Then, the char infiltrated green body is infiltrated with molten silicon to form a continuous matrix throughout the composite. The silicon in the continuous matrix is reacted with the carbon char to form silicon carbide.

Boron carbide based ceramic matrix composites

The present invention is a composite material and process to produce same. That material comprises a fibrous structure which is initially predominantly coated with elemental carbon; that fibrous structure is then subsequently predominantly coated with at least one ceramic material, e.g., boron carbide, which is non-reactive with silicon. The composite material also comprises a silicon matrix which is continuous and predominantly surrounds the fibrous structure, which has been initially predominantly coated with elemental carbon and subsequently predominantly coated with at least one ceramic material. The matrix which has a fine grain crystalline structure of predominantly 20 microns or less in size. The at least one ceramic material is discontinuous within that matrix. The fibrous material pulls out of the elemental carbon, which initially predominantly coats that fibrous structure, when the composite is subjected to fracture.

Disclosed is a ferrous metal article having a protective, adherent, wear resistant coating of metallic oxides and a method of forming a protective, adherent, wear resistant coating of metallic oxides on an iron-chrome article. The coating desirably has a thickness of from about 12.7 to about 102 microns (&frac12; mil to about 4 mils) and is formed by exposure of the article to an oxidizing atmosphere, preferably air, preferably during heat treatment of the article.
