ABSTRACT:
A test blade and a method for fabricating the test blade are presented for use in calibrating a tomography system configured to inspect turbomachine blades for defects. The test blade may include a three-dimensional fiber blank and a polymerized resin. The blank may be created by weaving synthetic material fibers. The resin may be configured to be injected into a mold as a liquid where the resin may polymerize around the fiber blank. The test blade may be configured to be modified to include particular defects such as cut fibers and/or cavity defects which are perceived by the tomography system. The dimensions of the cavity defects may be substantially created by pulling two or more fibers apart at a specific distance with a spreading tool.
