Wilhelmy plate experiments were performed with carbon fibres submitted to different degrees of surface treatment and various viscous fluids. The relative solid-liquid velocity was varied between 20 and 260pm s-~. The recorded force shows contributions from hydrodynamics (connected to the fluid nature and viscosity and to the interfacial velocity) and surface-related effects (surface energetics of fibres and liquids). The use of viscous fluids in the simulation of the fibre-liquid interaction involving hot polymer melts and reactive monomers is discussed.
