Determining the Orientation of Anisotropic MaterialsUltrasonics probe direction of tile fibers. Hand-held acoustic transducer determines fiber orientation of heat resistant tiles. Transducers head placed on outer surface of painted tile. Signals from receiving transducers displayed on two-channel oscilloscope. Application suggests extending technique to inspection of other anisotropic materials. Plywood and fiber/epoxy composites examined to determine fiber direction; ultrasonics used to find direction of roll in sheet metal and other rolled products.
