Description	Článek prezentuje superpozici ustálených a oscilačních smykových toků, která poskytuje důležité poznatky v charakterizaci kompozitních systémů. Experiment byl proveden na polymerních kompozitech s částicovým keramickým plnivem. Superponovaný tok zvyšuje viskoelastické vlastnosti daných materiálů; zatímco u čisté polymerní matrice je průběh monotónní, se zvyšujícím se přídavkem pliva se stává komplikovanějším. (cs) 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-plate rheometer; 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.
