摘要
本文研究了不同加载速率v对工程塑料(PBT、PSF、PEI、PES)拉伸性能的影响。实验结果显示,四种不同工程塑料的抗拉强度随拉伸速率的变化具有相似的变化趋势:开始时,抗拉强度随拉伸速率的增大而迅速增大,当达到某临界值时,抗拉强度缓慢增大。
This paper studied the effects of the different loading rate (v) for engineering plastics ( PBT, PSF, PEI, PES) tensile properties. The results showed that four different engineering plastics with a tensile strength of the rate had the same trend. At the beginning, the tensile strength increased rapidly with the increasing rate, when they reached a certain critical value, the tensile strength increased slightly.
