Over the last 50 years, the aerospace and aircraft industries have used silicone in an ever-growing number of applications. Silicone inherently has high dielectric strength (typically ≥ 500 V/mil) and a large coefficient of thermal expansion (CTE), allowing it to absorb stresses during thermal cycling.
Adhesive bonding can be used to assemble identical materials or materials of different types; the purpose of such an assembly is to transfer mechanical loads in a given environment.
Composite materials, including carbon fiber, are often preferred over conventional materials such as metal because they are lightweight, versatile and resilient.
PPG recently announced that the PPG Industries Foundation has donated $15,000 to the Air Force Museum Foundation for construction of a fourth major building.
