Experimental Study on Mechanical Properties of CFRP Tendon
According to GB/T 26743-2011, 37 different surface state of 8 mm CFRP tendons are made on the mechanical properties test to determine some mechanical properties such as tensile strength, elastic modulus and elongation rate. The experiment process, experimental method and failure state are introduced in detail. Considering many factors to the experimental results, the results are analyzed from production process, binder type, anchorage length and fiber species. The results showed that stress-strain curves are straight lines and the failure mechanism has brittle fracture characteristics. From the point of view of detection method, anchor end must adhere sand in accordance with anchorage of resin sleeve in national standard when testing. CFRP tendon of fiber volume ratio 63%-65%, thread depth of which is suggested to be 0.3-0.4 mm, is recommended to produce by one molding process. Anchorage length is suggested to be 200 mm above.
