Abstract
The emerging challenges brought about by sustainability requirements are leading to new applications of renewable resources. The recent development of joining technologies for renewable materials and composites like wood or bamboo or a combination of both with natural fibers open new avenues for sustainable applications. These advancements in joining technologies are new and unfamiliar compared to conventional techniques, posing specific challenges for inspection. By reason of the great advantages of non-destructive testing (NDT) methods for example for the quality control in later production, their use to characterize renewable materials and composites including the properties of their joints is envisaged. Possible use cases for inspection of renewable materials and composites are described with particular regard to special requirements of selected NDT methods. These may include conventional techniques such as ultrasonic testing, radiography, magnetic particle inspection, as well as further developed, advanced techniques like radiographic computed tomography, phased array ultrasonic testing, acoustic testing, active thermography, etc., each with their own aspects, strengths and limitations. The focus is on understanding the specific demands of the application and selecting appropriate NDT. The possibilities and limitations of NDT for particular applications are examined, highlighting relevant aspects that often vary significantly across different testing methods. Factors such as material composition, joint geometries, testing speed, and environmental conditions are taken into consideration. This analysis helps to determine the capabilities of NDT in meeting the specific needs of the application, identifying potential areas of opportunity and potential challenges. NDT techniques that most likely can be used for the characterization of sustainable, renewable materials are identified. Fundamental considerations, along with initial findings, are presented. The results obtained so far demonstrate the potential of NDT in addressing the unique requirements of the new joining technologies for renewable materials and composites. However, further research and development are necessary to refine the inspection techniques and optimize their performance. Shown results provide the basis for further exploration. Looking ahead, an outlook is provided, outlining future directions and opportunities for the advancements. This includes refining test environments, enhancing the sensitivity and accuracy of NDT methods, and expanding their applicability to different materials and joining configurations. By addressing these issues, NDT can play a crucial role in the successful implementation of new joining technologies in development of sustainable materials for a wide range of applications. Finally, the non-destructive nature of the testing also saves valuable raw materials and thus reduces CO2 emissions.
