COSI

COSI (Composite String Orientation Indicator) is a tool used mainly in manufacturing and engineering to determine the precise direction or orientation of a composite string or fiber within a material. It helps ensure that fibers are aligned correctly during production, which is crucial for the strength, durability, and performance of composite parts. By accurately identifying fiber orientation, COSI enables technicians to verify quality and maintain consistent standards in engineered products. Essentially, it provides a clear, reliable way to check how fibers are positioned inside complex materials.
