摘要
研究了在不同加载速率下低密度聚乙烯薄膜横向、纵向拉伸强度和断裂伸长率的变化规律。实验结果表明,其横向拉伸强度和断裂伸长率大于纵向拉伸强度和断裂伸长率;拉伸速率对拉伸强度和断裂伸长率没有显著影响。
The influence of loading rate on the tension properties of the low - density polyethylene film in longitudinal and landscape orientation was studied. It showed that the tension strength and the elongation at break in landscape orientation are larger than those in the longitudinal, and the effect of extension rate on the tension strength and the elongation at break is not significant.
