Abstract：Based on the national standard GB/T 17911-2018 Methods of test for refractory fiber products, the tensile strength test of elastic blanket material in LNG storage tank was conducted by the destructive tensile test method. The average value of tensile strength was obtained, which was compared with the value required in design. The results showed that the tensile strength of elastic blanket material could meet the requirements of the engineering design. In addition, according to the analysis of tensiondisplacement curve measured in the test, the elastic blanket started to fracture after reaching the peak value during the elastic deformation period, and finally the material was completely disconnected. The curve in the elastic deformation area of the elastic blanket material was steep, while the curve during the fracture period was smoother.
