  • According to the provisions in Fiber Reinforced Composite Bars for Structural Engineeing(GB/T 267432011), mechanical property tests of CFRP bars with different diameters are made to determine some mechanical properties such as tensile strength, elastic modulus and elongation rate.The experimental process, method and failure state are introduced in detail.The results show that stress-strain curves are straight lines and the failure mechanism has brittle fracture characteristics.From the point of view of detection method, it is recommended that sand-gluing treatment should be done for the anchor end to ensure that the adhesive anchor does not fail when testing bars in accordance with anchorage of resin sleeve in national standard.Unilateral anchoring length is suggested to be 200mm when the adhering sand with a diameter of less than 7 mm is firm.
