Ultrasonic Imaging of Internal Structures of a Fiber Steered Composite Panel
Fiber placement as a manufacturing method for composite parts has gained popularity in recent years. Fiber placement has been used not only in the manufacturing of military hardware such as the inlet duct of the joint strike fighter 1 and the landing gear pod fairing of the C-17 transport2, but also in the manufacturing of lighter aircraft for civil aviation3. Fiber placement technology has a number of advantages over hand layup processes. It can be used to fabricate composite components with highly complex shapes in one automated, computer-controlled program. The savings in labor and low scrap rate combine to reduce the production costs by as much as 50%. The computer-controlled robotic operation also leads to a more consistent product.
