Creep and Impact Properties of PA6 with Montmorillonite and Halloysite Nanoparticles
Original language description
Polyamide 6 matrix was reinforced by particles on base of a layered montmorillonite (MMT) and halloysite nanotubes (HNT). Experiments were focused on influence of different structure parameters of fillers on stiffness and toughness of thermoplastics composites. Uniaxial tension creep tests under constant load at different stress levels were conducted. Results of creep tests clearly demonstrate, that a small amount of MMT and HNT prevents from growing creep deformation. Rigid nanoplatelets create barrierfor conformation changes and motion of polymer chains. Results show a decrease of toughness of PA6/MMT and PA6/HNT nanocomposites in comparison with a neat PA6. Immobilisation of polymer chains by nanoparticles in those types of nanocomposites forbids growth of plastic deformation, which absorbs fracture energy.
