Abstract: Based on the pull-out tests of three fabrics with different fabric density and three-point bending tests of fabric reinforced cement, studied the in t erfacial bonding condition and the influence of fabric density on interfacial bo nding properties of fabric reinforced cement compoites, discussed the effe ct of the twist of yarn on i t.The results show that the influence of fabric density on the interfacial bondi ng properties is dual.Among the fabrics used in tests,the interface bonding proper ty of nylon fabric with warp density 80 threads/10 cm and weft density 50 threa ds/10 cm reinforced cement composites is relatively the optimal.
