摘要

The phenomenon of inter-yarn friction plays a crucial role in determining the behavior of woven materials. However, understanding and modeling this phenomenon remain complex due to the numerous parameters involved-such as normal force, velocity, angles, and sizing agents. To better analyze the influence of these various parameters on friction, a friction test bench without force sensors was developed, along with an associated finite element model. Motor control is used to vary carriage speed. An automatic image analysis method is used to measure the slippage between fiber tows. The model relies on an Arbitrary Lagrangian Eulerian (ALE) formulation, which provides simplified handling of inter-yarn contacts and slippage, while offering enhanced computational speed and robustness compared to a model based on a Lagrangian formulation. By comparing simulation results with experimental curves, a contact law was formulated, and its parameters were identified.
