Heat and Wear-Resistant Materials
Carbon composites are routinely used in airplane brakes where
Carbon composites also provide self-lubricating features that promote extended life. For example, a specialized brake pack for the V-22 Osprey aircraft was developed in cooperation with Parker Hannifin using a carbon composite coated with silicon carbide.
This brake surface offers exceptional friction performance over a wide temperature range and excellent wear results.
The high thermal conductivity coupled with low thermal expansion and high strength gives this material exceptional thermal shock resistance along with very high friction properties

Rocket Nozzles

Pyroid® pyrolytic graphite has a long history of successful operation as a material of choice for solid propellant rocket exhaust nozzles, throat inserts, and guide vanes.
Pyrolytic graphite is an excellent thermal insulator in the
direction normal to the deposition layer planes. The material offers the lowest known erosion resistance of any material operating under severe conditions up to flame temperatures of 3,600

The best erosion resistance is achieved by exposing the pyrolytic graphite layer plane to the hot discharge gases. When used in this orientation for best erosion resistance, the inherent insulating properties in the material leads to a rapid rise in
Pyroid® pyrolytic graphite is also available as a nozzle throat insert, compatible with most composite

materials. These inserts are orientated to better withstand mechanical erosion of the hot exhaust gases while promoting rapid thermal transfer away from the hot zone.
Because the throat geometry remains constant throughout the propellant burn, this promotes a more predictable burn of the propellant grain, even under high acceleration loads.
Studies have shown that for
These advantages, coupled with Pyroid® pyrolytic graphite's high strength, high thermal conductivity, low thermal expansion, and low weight are keys to extending the range of today's advanced rocket technology.
