The paper represents the situation of internal friction researches for polymer blends and composites, and analyses specially the correlation between internal frictionbehavior and microstructure.
Based on a slab caster equipped with hydraulic oscillators, the transient mould friction force was measured, and the characteristics of periodical behavior of mould friction force is discussed.
