New experimental device for measuring the inter-fiber transversal friction

The mechanical behavior of fibrous structures depends on the inter-fiber friction. In the scientific literature, many researchers have studied this kind of friction, however all of them focused on the inter-fiber friction in only two directions: longitudinal-to-longitudinal (l-l) and longitudinal-to-transversal (l-t). Hence, there are no studies, up to now, focusing on transversal-to-transversal (t-t) direction. For this reason, an experimental device was developed to evaluate the transversal inter-fiber friction. The obtained results would allow characterizing and modelling this type of friction.
