| The fabric reinforced concrete as a new-style of cement based composite is a new research problem abroad and at home. The advantages of fabric are based on the possibility of designing the composite characteristic and reducing weight while increasing the quality such as strength, toughness of the concrete and resisting corrosion. In this dissertation, the effect of fabric on the properties of anti-crack and obdurability is discussed by studying the mechanical performance of the composite of polyester (PET) and polypropylene (PP) fiber fabric reinforcement and mortar or concrete matrix.1. The leno of PET and PP fiber are manufactured. Different configuration or structure fabrics such as planar and three-dimensional fabric are woven on the conventional loom. 24 fabrics in all are manufactured.2. Interfacial bonding strength between PET and PP fiber with cement matrix is evaluated through yarn pull-out test and three-point-bending test. The adhesive for leno setting is selected and optimized as well. The results show that the fibers'bonding to matrix is fairly high, and the bonding effect of adhesive A is quite good.3. The obdurability of composite of mortar matrix and leno fabric reinforcement are studied with tension and bending test. The results indicate leno can improve the mortar property of anti-cracking evidently and enhance the ductility mainly. The composite reinforced with glass fiber leno fabric has high strength, while PET, PP high ductility.4. The reinforce properties such as splitting strength and flexural strength of the composite combining with different configuration fabrics as reinforcement and concrete as matrix are tested. Experiment shows fabric has increased the strength and toughness of the concrete, solid fabric is better than planar fabric. In terms of the flexural strength, the shape of"T"fabric is highest, the shape of"+"second, and planar fabric lowest. In terms of the splitting strength, the shape of"T"and"+"fabric are rather well.
