A DISCUSSION ON RHEOLOGICAL MODELS OF GLASS FIBER REINFORCED POLYPROPYLENE

In the present paper the creep curves of glass fiber reinforced polypropy-lene are measured by the creep test in tensile conditions.Based on the proposed Theological models the constitutive equations of creep are constructed and the rheological paraments are obtained. The effects of temperature and the quantity of glass fiber upon the Theological behavior are further discussed.
