Influence of the Frequency Behavior of Arall and Glare on the Ultrasonic C-Scan Inspection
Fibre Metal Laminates (FML’s) are new types of materials which are of interest to the aerospace industry. Two examples are ARALL and GLARE. The materials are composed of thin layers of aluminum bonded together with aramid (ARALL) or glass (GLARE) fibre reinforced layers (which will be called the aramid or the glass layer, see figure 1). The materials are lighter than aluminum sheets of the same (total) thickness and have a superior fatigue behavior.
