On the dynamic mechanical behavior of nylon 66

摘要: The dynamic mechanical properties of nylon 66 films and fibers have been examined, as a function annealing drawing, with Vibron viscoelastometer. It is found that the α′ transition little affected by treatments, but increase in orientation causes to move higher temperature. Experiments, X-ray diffraction samples at elevated temperatures, lead conclusion triclinic hexagonal phase change does not contribute significantly transition. Samples cut parallel perpendicular drawing direction film, used show curves tensile modulus versus temperature, for directions, cross neighborhood This observation discussed relation suggestion glass 66.
