Creep resistance of HDPE/PA66 system: effect of PA66 phase geometry and graphite nanoplatelets addition
Original language description
Microfibrillar composites (MFC) with in-situ generated short polymeric fibres feature, unlike composites containing inorganic rigid fibres/particles, lower creep resistance in comparison with analogous blends containing spheres. Further attribute is unprecedented decrease in creep resistance of the blend by graphite nanoplatelets (GNP). Explanation of this behaviour of the HDPE/PA66/GNP system consists in characterization of structure and finite element analysis (FEA) „mapping“ the effect of reinforcement and interface parameters on creep behaviour. Lowering of reinforcement modulus and its viscoelasticity may lead to worse creep resistance of fibrous composites. FEA also indicates marked negative effect of the soft interface, i.e. GNP-reduced crystallinity of HDPE near the interface, on creep resistance of the spheres-reinforced system in contrast to MFC. Structural changes are indicated by polarized light microscopy, SEM and TEM. The results reveal so far unknown complexity of the performance of polymer/polymer composites which may cause unprecedented antagonistic effects.
