| Title of the article | Prediction of deformation in time of high polyethylene fibers with different temperatures |
| Abstract. | The paper considers the important task of forecasting the deformation of high-strength polyethylene fiber over time at different temperatures. The need for ongoing research is due to the optimal choice of the polymer matrix to create a composite material acting as a «whole», i.e. without cracking of the polymer matrix during the time in the application loads close to critical. The object of this study was many filament high-strength polyethylene fiber. When using the selected method of analogy, the problem of predicting the creep for a given temperature and stress is reduced to finding the coefficients of reduction, based on experiments that establish the relevant time scales of deformation. To describe the behavior of the polymer was accepted model of hereditary-elastic material with creep kernel of Abel. After processing the experimental data the regression function describing the behavior of the polymer material. Having obtained a coefficient reduction can solve the problem of predicting the behavior of materials under conditions most close to the performance, for example, for large values of time interval values or higher temperatures. Thus, the results of the experiments and numerical analysis can be assumed that the polymeric material under consideration is classified as «simple», that allows knowing the coefficient of temperature-time analogy, to predict its behavior over time at different temperatures and prolonged operating time. |
