The Influence of Temperature on Toughness of PA6/POE-G-MAH/OMMT Blends

Abstract:

Composite materials of POE-g-MAH，OMMT and PA6 were prepared by blending technology. Thermodynamic performances of PA6/POE-g-MAH/OMMT were determined in different temperature by SEM, TEM and XRD. The experimental results indicate that the notched impact strength of bends with the same component gradually increases as temperature increases in the range of -37 °C-23°C ,and with POE-g-MAH/OMMT content increasing, the impact strength keeps rising and stress whitening occurs; But at 50°C, higher than the glass transition temperature of PA6/POE-g-MAH/OMMT , plastic deformation begins easily and strongly. Because POE-g-MAH to a certain content, the stress state changes from plane strain to plane stress, make the ability of plastic deformation increasing .The plastic deformation absorbs many impact energy, and make the stress whitening phenomenon.
