Introduction Textile-reinforced flexible composites, usually called coated fabrics or laminated fabrics in textile industry, have been widely used in many engineering structures due to their excellent mechanical proprieties.
Now days, the flexible composites have been widely applied in many fields, i.e. civil engineering, architecture, aerospace engineering and other inflatable structures [1,2].

Also, the addition of fibers in a concrete mix significantly improves many of its engineering properties, namely, tensile, flexural, impact, fatigue and abrasion strength.
To facilitate its use in reinforced cement and concrete, the engineering community requires a better knowledge of many properties of BF.BF is a new kind of inorganic fiber materials which shows prosperities of high tensile strength, high elastic modulus and excellent anti-corrosion and so on, compared with common fibers used such as PP fiber.
