Název v původním jazyce

Superposed flow of CIM compounds

Popis výsledku v původním jazyce

In the present paper ceramic powder (zirconia) was mixed (10 to 50 vol.%) with polypropylene, paraffin and stearic acid in elastic extruder. Steady and oscillatory shear flow properties of these materials in the molten state were measured on a cone-platerheometer; parallel superposed steady and oscillatory shear flow experiments were also carried out. Moreover, flow properties at high shear rates were measured on a capillary rheometer. The effects of powder content, shear rate/angular frequency and temperature on various flow properties were investigated. The studied filled systems showed remarkable non-Newtonian behaviour and apparent yield stress. Viscoelastic properties of the studied materials, such as storage modulus and dynamic viscosity, were influenced remarkably under the superposed shear flow at low shear rate and angular frequency, and they showed significantly different behaviour from unfilled and fiber-filled systems.
