The friction states between yarns affect the stress transferred in fabric and the fabric structure significantly affects the tribological properties of composites. In this aricle, the effects of fabric structure on yarn pull-out property and tribological performance of composite were thoroughly studied. Four different fabrics with same tissue cycles number and thread count (2/2 double twills, 1/3 twill, 4-shaft satin, and 4-shaft reinforced
satin) were used to evaluate the yarn pull-out property in fabric and the tribological performance of corresponding composites. The results indicate that fabric structure has asignificant effect on the yarn pull-out property in fabric. In particular, the yarn pull-out property of 4-shaft reinforced satin was best in the four fabrics structure used in this
article owing to the excellent integrity of the 4-shaft reinforced satin fabric structure and the distribution characteristics of the fabric intersection points. The tribological performance of the 4-shaft reinforced satin fabric enhanced composites were positively correlated with yarn pull-out property because the yarn pull-out property in fabric played an important role in energy dissipation and load carry capacity.
