Statistical Analysis of Mechanical Properties and Processing Parameters of UHMWPE Fibers

At present, the research on improving the performance of ultrahigh molecular weight polyethylene fiber mostly starts from a single process or single factor, and lacks comprehensive cross-process research. Based on a large number of experimental data, this paper studies the relationship between mechanical properties and processing parameters of ultrahigh molecular weight polyethylene fiber (UHMWPE) by factor analysis. After the dimensionality reduction of processing parameters, three main influencing factors (including most of the processing information in the whole process) were extracted, and the main influencing factor was determined to be the draw-down ratio by correlation analysis and F-test. On this basis, the multiple linear regression model of fiber properties and processing parameters in the whole processing process is established, and the mechanical properties of the fiber can be predicted by the processing parameters.
