Composite materials have seen, and will continue to see, increased usage, particularly in the realms of automotive and aerospace where increasingly tight emissions standards call for lighter weight structures. These structures will also have to be made at a lower cost than previous iterations, particularly for mainstream automotive concerns. The production of composite panels is a complex, multi-step process consisting of a number of interactions. Variability is present within the raw materials and throughout the production process. Quality is intrinsically linked to both production rate and cost. Fewer defective parts means fewer concessions and less scrap, thus presenting a cost saving. Present defect rates are relatively high for composites when compared to metallic structures. Quality in composites also does not assume defect-free conditions, but rather acceptable levels of features and variations which occur during production.
