  • Elastic modulus of fibers spun from the binary polymer blends
    Gregor-Svetec, Diana
    Among mechanical properties of polypropylene fibres, spun from the blend of medium molecular weight CR-polymer with added high molecular weight polymer in the composition range of 10-50 wt %, special ... interest is focused on the elastic modulus in this paper. In the case of two-phase composite system, the resultant modulus is a function of the moduli of the individual pure components, the volume of the weight fraction, the geometry and packing of the disperse phase and the Poisson ratio of the matrix. In present paper only several representative equations for the calculation of elastic properties of a two-phase systems are presented. This present work is concerned with applicability of those theories to the specific case, drawn polypropylene fibers spun from blend of different polymer grades. Predicted elastic modulus calculated from the Kleiner's simplex equation is compared with the elastic modulus of drawn fibers determined from the stress vs. strain curve.
