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.

An actuator mechanism for a braking system employing multiple disc brakes to insure an air gap between the pressure plate of the brake stack and the piston head of a piston. The piston is mounted in a cylindrical housing with an end wall to which a rod is secured. The rod extends into the piston and has a hardened ball on its end for engagement by a deformable sleeve. The deformable sleeve is connected to an outer cylindrical tube for movement therewith. Such outer tube has a flange on one end that slidably engages the cylindrical wall of the piston and a ring on the other end that is adapted to engage an annular spring retainer member slidably mounted on the outer tube. The piston has an inwardly extending annular abutment that engages the retainer member with a coil spring encircling the outer tube having one end engaging the flange and the other end engaging the retainer member to provide widely spaced footprints for the spring. Such spring biases the piston after a braking action to re-establish the air gap.

A heat shield installation on a tire supporting wheel and brake assembly having a rim member with an inner surface that surrounds a heat sink composed of stator and rotor brake discs. A plurality of circumferentially spaced drive keys are located between the heat sink and the inner surface of the rim member with such keys slidably mounting the rotor discs. A heat shield is located between the inner surface and the drive keys with a plurality of circumferentially spaced spacers secured thereto. Fastener members interconnect the drive keys to the rim members through the spacers while securely locking the heat shield radially and axially relative to the rim member of the tire supporting wheel.
