Abstract

Fiber-reinforced polymers show a continuous material degradation under cyclic loading, which is why damage development has to be investigated for an exact assessment of fatigue properties. In order to obtain information on damage in the internal volume, conventional mechanical test methods require accompanying support by further developed techniques. In this study, a methodology for in situ computed tomography has been developed and applied to glass fiber-reinforced polyurethane. Polyurethane has advantages over epoxy in terms of impact strength, damage tolerance and abrasion, which are important for various applications. Fatigue properties, on the other hand, are largely unknown. Optimized imaging parameters for computed tomography have been established in order to obtain detailed 3D volume images suitable for analysis. The 3D volumes of the damage state were recorded according to defined fatigue load steps and used to evaluate and correlate the damage development with the mechanical properties. The results confirm known damage characteristics of fiber-reinforced composites but also show material and structure-related differences in crack formation and propagation.

Daniel Hülsbusch, born in 1986, studied Mechanical Engineering with an emphasis on technical management and materials science at TU Dortmund University where he received his Dipl.-Ing. in February 2013 after focusing on fiber-reinforced polymers at the BMW group. Since then, he has been working as a research assistant and group leader for “Composites” at the Department of Materials Test Engineering (WPT) at TU Dortmund University, Germany, and was appointed general Senior Engineer in 2015. His research is mainly focused on the fatigue properties of fiber-reinforced polymers, including the determination of deformation and damage behavior by combined destructive and non-destructive testing, and approaches of lifetime prediction.

Selim Mrzljak, born in 1991, studied Mechanical Engineering and received an M.Sc. at TU Dortmund University with a focus on machine technology and materials science in 2018. Since 2015 he has been working as a student assistant and research assistant (as of 2018) in the Department of Materials Test Engineering (WPT) at TU Dortmund University, Germany, in the field of fiber-reinforced polymers and hybrid structures. His research is mainly focused on hybrid laminates made of lightweight metal and fiber-reinforced polymer, investigating the mechanical properties and deformation induced degradation behavior by combined destructive and non-destructive testing.

Prof. Dr.-Ing. Frank Walther, born in 1970, studied Mechanical Engineering majoring in Materials Science and Engineering at TU Kaiserslautern, Germany. There he completed his PhD on the fatigue assessment of railway wheel steel in 2002 and his habilitation on physical measurement techniques for microstructural-based fatigue assessment and lifetime calculation of metals in 2007. At Schaeffler AG in Herzogenaurach, Germany, he was responsible for Public Private Partnership within Corporate Development from 2008 to 2010. Since 2010, he has been Professor for Materials Test Engineering (WPT) at TU Dortmund University, Germany. His research portfolio includes the determination of process-structure-property-damage relationships of metal- and polymer-based materials and components under fatigue loading from LCF to VHCF range, taking the influence of manufacturing and joining processes as well as service loading and corrosion deterioration into account. Prof. Walther has published more than 260 research papers and conference proceedings and maintains close scientific contact with institutions and industries in materials science and engineering field worldwide.
