Analysis of PA 6 nanocomposites — indentation and creep behavior as a function of temperature

and load level using different indentation techniques (in English)

Polimery 2014, No 10, 722


DOI: dx.doi.org/10.14314/polimery.2014.722

Summary

The short-term performance (Martens hardness and indentation modulus) and the time-dependent creep behavior of polyamide 6 (PA 6) and two PA 6 nanocomposites containing 3.5 wt % montmorillonite (MMT) or 5 wt % halloysite nanotubes (HNT) were analyzed by different depth-sensing indentation techniques in the nano-, micro- and macro-range of loading as a function of applied load (0.08— 100 N) and temperature (-80—60 °C). Additionally, WAXD and DSC measurements were made to establish the morphology-property relationships of the investigated materials while taking into account the skin-core structure of the injection-moulded samples.


Key words: depth-sensing indentation techniques, Martens hardness, indentation modulus, creep behavior, skin-core effect, temperature, polyamide 6, nanocomposites
