Damage tolerance safety concepts and corresponding inspections procedures are today?s standard for metal aircraft structures. The direct application of these concepts to composite materials is further limited by two additional facts: the scatter of material properties due to manufacturing defects and the sensitivity of the material to impact damages. Here, the on-board installation of Structural Health Monitoring (SHM) systems might be the key technology to increase the confidence level of predictions. However, pure SHM systems are not sufficient to assess structural health. A complete system should monitor, assess and assure (i.e. control) the structural health (i.e. strength and stiffness) by drawing consequences for further use of the damaged structure. The selection and the detailed design of such Structural Health Control systems must be in accordance with design objectives and safety concepts.
