| Abstract: | According to the requirements of GB/T 3362-2017“Test Methods for Tensile Properties of Carbon Fiber Multifilament”and JJF10591-2012“Evaluation and Expression of Uncertainty in Measurement”,the uncertainty of tensile strength measurement of domestic T800 carbon fiber multifilament was evaluated.The results show that the expanded uncertainty of tensile strength of domestic T800 carbon fibers is(5923±228)MPa,which mainly comes from the repeatability of linear density calculation and measurement results;The stability of measurements can be ensured by adopting appropriate measuring equipment,standardizing the sample preparation process,placing the spline in the curing test process,and selecting skilled testers for sample preparation and measurement. |
