The increasing demand for weight reduction in aeronautics and automotive engineering meets COTESA through a broad spectrum of fiber composite components for CFRP primary structures, fiberglass interior and exterior components as well as components such as drive shafts and tanks. The standard production of parts and assemblies for aerospace, automotive and industrial applications ranges from 1 to several thousands per year.
As a supplier, COTESA GmbH produces fibre composite parts for structural applications in the Prepreg autoclave procedure under the quality-technical requirements of the aviation industry. For example, profile structures of many different cross-section shapes form a great part of the component range. One challenge here is in compliance with the required component thickness tolerances in the radius area of U-shaped structures.
