GB/T 38534-2020 "Test method for tensile properties of oriented fibre reinforced polymer matrix composite materials at ultra-low temperature"

This standard applies to the determination of the tensile performance of directional fiber reinforced polymer-based composites in an ultra-low temperature environment from -196 ° C to -269 ° C. The standard specifies test equipment, specimen preparation, test procedures and result calculation, focusing on evaluating the tensile strength, resilience modulus, Poisson's ratio and failure strain of the material. This standard is suitable for material performance evaluation in extreme environments such as aerospace, and provides technical support for the development and application of related composites.
