摘要
本文用动态粘弹谱、静态力学性能测试和密度梯度法,研究了热处理对聚醚醚酮力学性能的影响规律.发现聚醚醚酮α峰位置、屈服应力、T_g 到T_m 间的储能模量随结晶度增大而增加;β峰面积、断裂伸长随结晶度增大而下降.
The mechanic properties of polyether ether ketone(PEEK)subjected to heattreatment have been studied by dynamic viscoelastic curves,static mechanic measurementsand density gradient method.The experiment results show that as the crystallinity increase,the sample's yield stress,the position of α-transform peak and the storage modulus be-tween T_g and T_m increase;but the elongation at rupture and the area of β-transform peakdecrease.
