Abstract Scope |
Modern composite structures are increasingly used in automotive, aerospace, and building industries due to their lightweight and high-performance properties. Reliable lifetime estimation is crucial, necessitating in-depth characterization of fatigue behavior and damage mechanisms using modern evaluation tools and novel techniques. Such are presented in the context of classical and natural fiber-reinforced polymers, cellulose-based composites, and hybrid structures like fiber metal laminates. The characterization techniques focus on investigating damage mechanisms under laboratory-scale application scenarios using tools such as digital image correlation and thermography. Due to the complexity of composites, critical ambient conditions, including temperature and humidity, are examined using climatic chambers to provide a comprehensive overview of mechanical and structural properties. To characterize the fatigue damage at a volume level with high resolution, in situ testing techniques using computed tomography and sequential fatigue testing are applied to gather essential information about damage initiation and evolution. |
