Even if they are very small, faults in composite materials may have serious effects on the operating behaviour and the appearance of resultant components. This is especially true where maximum demands are made on surface regularity. Manufacturers are facing the task of using efficient and economical test technologies in addition to improving production techniques. A new type of test method makes visible even the smallest faults in composite materials using laser light. The system takes an automatical test decision, records the results and gives signals for production control.
