	1	Biomimetic artificial cartilage:fibre-reinforcement of PVA hydrogel to promote biphasic lubrication mechanism显示文摘The fibre-reinforced structure in synovial articular cartilage plays an important role in enhancing the fluid load support in the biphasic lubrication mechanism.Poly(vinyl alcohol)(PVA)hydrogel is a potential biomimetic articular cartilage material.In this study,PVA hydrogel was reinforced with PVA fibres to improve its frictional properties.By computational analysis,the position of the PVA fibre layer was examined with a migrating contact condition to reduce the friction coefficient.To improve the fibre reinforcement,a method for fibre placement was developed to retain the initial strain of the fibre in the hydrogel matrix.The experimental results showed that the fibre-reinforced PVA hydrogel with a surface fibre layer had a low friction coefficient of 0.031 in pure water.The fibre-reinforced PVA hydrogel successfully reduced friction coefficient.

	2	Influence of collagen fibre orientation on the frictional properties of articular cartilage显示文摘Articular cartilage has a unique collagen fibre network structure that exhibits both anisotropy and depth dependency.Collagen fibre orientation in a cross-section parallel to the articular cartilage surface may affect the lubrication properties of articular cartilage.The effect of collagen fibre orientation on the frictional properties of articular cartilage was examined through finite element analysis of the friction.Specifically,a three-dimensional fibre-reinforced poroelastic biphasic model was used to determine the influence of collagen fibril orientation on the frictional properties of articular cartilage.The simulations reveal that collagen fibre orientation has a significant influence on the deformation behaviour of articular cartilage in front of and behind the contact area.The coefficient of dynamic friction was lower in the direction parallel to the collagen fibre orientation than in the direction perpendicular to the collagen fibre orientation,regardless of the indenter speed.
