This paper proposes a methodology for measurement of fibre misalignment in composite
laminates based on the structure tensor of fibre orientations extracted from X-ray micro …

The meticulous reconstruction of three-dimensional (3D) braided composite materials
serves as a crucial foundation for achieving high-fidelity simulations. Nonetheless, the …

Understanding the three-dimensional variability of unidirectional composites is relevant to
the material performance and the development of advanced material modelling strategies …

Local variations in the random filament arrangement in carbon fibre bundles were
determined by optical microscopy and automated image analysis. Successive steps of …

Carbon fiber reinforced polymers (CFRPs) are increasingly being used in cutting-edge
technologies, thus rendering accurate material characterization essential. However, the …

Extensive experimental test programs are required for the characterization of textile
permeability, which is essential for the design of liquid composite molding processes. In this …

This study analyses the influence of the random filament arrangement in fibre bundles on
the resin flow behaviour. Transverse steady-state resin flow that occurs behind a liquid resin …

Automated image analysis of textile surfaces allowed determination and quantification of
intrinsic yarn path variabilities in a 2/2 twill weave during the lay-up process. The yarn paths …

Dry fiber placement has a large potential for manufacturing preforms for primary-load
components at minimum scrap rate and fiber crimp. Yet, challenging impregnation behavior …

This paper presents results of recent cooperative works at the ITM and IKTS on the 3D fiber
