发明名称 FIBER SHEET FOR REINFORCEMENT
摘要 PROBLEM TO BE SOLVED: To provide a high strength biaxial reinforcing fiber sheet for reinforcing a building capable of providing a high reinforcing strength, excellent resin impregnating ability, and easiness in handling in execution of work. SOLUTION: This fiber sheet for reinforcement comprises a textile formed of high strength fibers of 16 cN/dtex or more in tensile strength, and the textile cover factor Cf thereof shown by expression (a) is 800 to 1500, the cross rate Ct shown by expression (b) is 10 to 30%, the air permeability is 5 to 20 cm3/cm2. sec., and vertical and horizontal strengths are at least 35 t/m, respectively. Cf=(DW)1/2×Nw+(Df)1/2Nf---(a) Where, Cf: Textile cover factor, Dw: Warp fineness, (dtex) Df: Weft fineness, (dtex) Nx: Warp density (no. of warps/cm), and Nf: Weft density (no. of wefts/cm). Ct=(i×100)/(i+y)----(b) Where Ct: Cross rate (%), i: Number of crossing of warps and wefts of prefect structure, and y: Number of warps of perfect structure.
