N2 - Fiber reinforced polymeric materials are used for lightweight constructions during several decades. GFRP or CFRP, for example, are an integral part of cars, airplanes, or rotor blades of wind turbines even up to a high percentage of the total range of used materials. While in the early years the optimization of the design and processing techniques and the reduction of production costs were governing the design process, today issues of life-cycle costs, recycling, maintenance and quality control becomes more and more significant as well. Non-destructive testing (NDT) methods play usually and increasing role in all parts of the life cycle of a product including the design, manufacturing, lifetime and recycling. NDT techniques can be included into the quality management system, used for inspections and for structural health monitoring (SHM) applications. NDT data can even be used for a better control and operation of structures. However, this requires an early integration of NDT in the design phase, a definition of defects (type, size, and location) that are critical (Effect of Defect) and the determination of the Probability of Detection (PoD) of such defects. A combination of testing methods for quality control and inspection is beneficial including for example ultrasound, infrared-thermography, eddy-current, CT scanning, microwaves, vibration testing, and acoustic emission analysis. Very rarely, all the above-mentioned points - that can be considered as modules - are considered in the initial design phase of a structure what is leading to a loss of performance and can be cost-inefficient. Techniques and processes to include efficiently NDT and SHM methods into the life cycle of a product are in its infancies but this is of particular interest for fiber-reinforced polymers. It will be demonstrated how this process can be optimized in a holistic way giving examples from applications in different fields including automotive and aeronautic.
