    摘要: A method for making a carbon-carbon composite brake disc by infiltrating a porous carbon preform with a resin and carbonizing the resin-infiltrated preform at a high pressure of at least about 5,000 psi to form a densified carbon-carbon composite disc brake with a final density of at least about 1.9 g/cc. The porous carbon preform includes a plurality of fabric sheets having non-woven oxidized polyacrylonitrile fibers, pitch fibers, or rayon fibers and a basis weight in the range from about 1250 to about 3000 grams per square meter. The fabric sheets are needled together. The porous carbon preform is infiltrated with resin, which includes at least one of an isotropic resin or a mesophase resin.

    摘要: A system method of estimating health of aircraft brake system friction material includes sensing a temperature of the friction material, and supplying the sensed temperature to a processor-implemented thermal model that is configured to estimate friction material temperatures at one or more locations on the friction material. The estimates of friction material temperatures are supplied to a processor-implemented thermal oxidation model that is configured, based on the estimates of friction material temperatures, to estimate friction material loss due to thermal oxidation. Data representative of runway fluid exposure are supplied to a processor-implemented catalytic oxidation model that is configured, based on the runway fluid exposure, to estimate friction material loss due to catalytic oxidation. The health of the friction material is estimated based on the estimates of friction material loss from the processor-implemented thermal oxidation model and the processor-implemented catalytic oxidation model.

    摘要: In one example, the disclosure is directed to a method of determining a length of a wear pin in a brake assembly. The method includes obtaining an input image of a portion of the brake assembly, such as with a camera. The input image includes the wear pin and a reference object, and the reference object has a known dimension. A processor may determine, based on the input image, an image dimension of the reference object. The processor may determine, based on the input image, an image dimension of the wear pin. The processor may further determine, based on the image dimension of the reference object, the image dimension of the wear pin, and the known dimension of the reference object, an estimated measurement of the dimension of the wear pin.
