Relative Thermal Life and Temperature Index

1994-10-01
HISTORICAL
AS4851
This test method provides performance data on candidate insulation systems as a function of time and temperature. These data give engineering information on the wire insulation candidate relative to the performance of materials already in use with a backlog of experience. These tests expose candidate insulation systems to a wide range of temperatures for short and long periods of time, while measuring the degradation of its physical properties. For aerospace use, end-point proof tests include mandrel bend, water soak, and dielectric integrity.

Metal Clad Fibers for Electrical Shielding & Harness Overbraid

2008-03-25
HISTORICAL
AIR5464
Over the past decade several metal clad fibers and fabrics have been developed to provide aerospace vehicle designers with a conductive, lighter weight alternative to coated copper or steel for shielding and harness overbraids of electrical cables. Several of these candidates have been unable to provide the strength or thermal stability necessary for the aerospace environment. However, the aramid-based products have shown remarkable resistance to the rigorous environment of aerospace vehicles. Concurrent with these fiber developments, there have been changes in the structures of aerospace vehicles involving greater use of nonmetallic outer surfaces. This has resulted in a need for increased shielding of electrical cables which adds substantial weight to the vehicle. Thus, a lighter weight shielding material has become more critical to meet the performance requirements of the vehicle.

Investigation of Whisker Formation on Tin Plated Conductors

2004-08-23
HISTORICAL
AIR5444
This SAE Aerospace Information Report (AIR) shall be limited to general information about tin whisker formation on tin plated conductors. It summarizes the mechanisms of metal whisker formation and describes possible conclusions as related to tin plated conductors. It also provides a number of reference documents that describes research and observations of the whisker phenomena, recommendations to prevent its formation and conclusions. The investigation by this task group of AE-8D was initiated by a request of the Naval Air Warfare Center, Indianapolis, Indiana, to determine if the phenomenon of tin whiskers is a problem in aerospace wire and cable.
