Dynamic Viscoelastic Properties of Long Organic Fibre Reinforced Polypropylene in Molten State

Original language description

This paper deals with the dynamic viscoelastic properties of long organic fibre [aramid fibre (KF), polyvinyl alcohol fibre (VF) and polyamide fibre (PA6)) reinforced polypropylene in the molten state. Long organic fibres mixed with polypropylene fibresby an apparatus called a "fibre separating and flying machine" were compression moulded into 3mm thick composites. Dynamic viscoelastic properties of these composites were measured in the molten state using a rotational parallel plate rheometer. It was found that the dependence of angular frequency on storage modulus, G', for long organic fibre reinforced polypropylene is different from that of volume fraction of fibre, Vf and the relationships depend on the characteristics of the reinforcing organic fibres. The slope of the dynamic viscosity, eta' vs. angular frequency, omega curves increases gradually up to 45 degrees with increasing V-f. Influence of fibre content on dynamic viscoelastic properties depends on the organic fibre used.
