Airborne systems traveling at high altitudes and extreme speeds are subjected to a severe and unforgiving aerothermal environment. These systems must be able to withstand the large temperature fluctuations and high pressures that are associated with this type of flight profile in order to operate safely and reliably. Not only that, but they are also expected to survive the constant vibration, threat of hydrometeor impact and the relentless effects of aging. Fortunately, materials technology has advanced to a point where a variety of heat-resistant materials are available for use in the aerospace and defense industry. Read on to learn why high temperature composites are playing a vital role in the development and fielding of successful airborne systems.
