断裂应力
The measurements indicate that the weak-link of the PET fibres is the defeats on surface layer and their propagation and that the mechanical properties of fibre weak-links are low stress, low strain and low work of rupture according to the analysis of the typical tensile curve.
结果表明,涤纶纤维的弱节主要是表层缺陷及其扩展所引起的,其力学性能为低应力、低应变、低断裂功特征。
