    Viscoelastic Properties of Flexible Organic Fiber Composites

  • Original language description

    Molten HDPE was compounded with four kinds of high performance organic fibers: two types of aramid (KF), liquid crystalline polymer (LCP) and poly(vinyl alcohol) (VF), differing in their chemical structure and fiber lengths. From the SEM pictures, it isobserved that shape and size of these organic fibers maintained almost the same even after cutting in pellets, following the mixing process. VF/HDPE and LCP/HDPE systems show generally lower rates of increase of both storage modulus and dynamic viscositywith fiber content than KF/HDPE composites. Comparison of these functions at the fixed fiber content has shown that the most effective parameter, affecting the viscoelastic behaviour of organic fiber filled systems, seems to be their rigidity/flexibility in the molten state. The influence of fiber rigidity/flexibility becomes gradually lower with the increase of both strain amplitude and angular frequency. The parameters of the equations describing relationship between relative values o

    Viskoelastické chování kompozitů na bázi ohebných organických vláken

  • Czech description

    V této práci byl sledován pevnosti/pružnosti vláken na viskoelastické vlastnosti HDPE kompozitů. Jako plnivo byla použita LCP (liquid crystalline polymer) vlákna, PVAL vlákna a dva typy aramidových vláken. Bylo zjištěno, že flexibilita vláken se v kompozitech uplatňuje zejména při nižších deformacích. Koncentrace plniva má značný vliv na parametry modelů popisujících vztahy mezi viskoelastickými funkcemi a obsahem vláken.
