摘      要：The fibre-reinforced structure in synovial articular cartilage plays an important role in enhancing the fluid load support in the biphasic lubrication ***(vinyl alcohol)(PVA)hydrogel is a potential biomimetic articular cartilage *** this study,PVA hydrogel was reinforced with PVA fibres to improve its frictional *** computational analysis,the position of the PVA fibre layer was examined with a migrating contact condition to reduce the friction *** improve the fibre reinforcement,a method for fibre placement was developed to retain the initial strain of the fibre in the hydrogel *** experimental results showed that the fibre-reinforced PVA hydrogel with a surface fibre layer had a low friction coefficient of 0.031 in pure *** fibre-reinforced PVA hydrogel successfully reduced friction coefficient.
