Imitating steel bar reinforced concrete,fiber reinforced mortar bars replaced steel bars to reinforce cement mortar.Fabrics were fabricated with glass fibers and aramid fibers by hand.As the main bar,fiber reinforcing mortar bars were braided and laid in many ways.The aramid fibers were used in connection the main bars and braid the fabrics.The influences of braid and laid style about main bar in fabrics on the mechanical properties of fabric reinforced cement mortars were studied.The results show that the flexural strength and compressive strength of fabric reinforced mortars with the main bars braid in plait were higher than that of the main bars braid in interlacement.There was an optimal value in the number of main bar of fabrics laid along(the length) and thickness direction.Above or below this value,the reinforcement efficiency would decease.Moreover,the thinner main bar had relatively higher reinforcement efficiency.
