Effect of load and twist on filament packing in three-strand aramid fibre ropes: a micro-CT study
Year: 2025
Type: conference-paper
Abstract: This study investigates how varying rope and strand twists influence the filament packing fraction in three-strand Aramid fibre ropes. Micro-computed tomography (micro-CT) scanning was used to visualize and quantify filament arrangements under different twist configurations and loads. High-resolution CT-scan image segmentation enabled the calculation of local filament packing fractions. Results indicate that twist parameters strongly affect how tightly filaments pack inside strands, particularly when a tensile load is applied. Higher twist levels often lead to a more compact internal structure, whereas lower twist levels introduce voids and an uneven arrangement. Under tensile loading, additional compaction is observed, especially at strand-to-strand interfaces. The findings help in understanding how twist geometry and applied tensile load redistribute filaments in a three-strand configuration, providing insights into load sharing, potential filament slip, and internal damage – all critical factors in assessing rope performance and service life.
