APPLICATION OF TORSIONAL VIBRATION TECHNIQUE TO STUDYING VISCOELASTIC PARAMETERS OF POLYMERIC COMPOSITIONS IN CURE

The calculation technique of components for the complex shear modulus has been developed with studying a sample by free torsional vibrations with consideration for relaxation processes occurring in high elastic region. For polymeric compositions on the basis of epoxy oligomer with various contents of curing agents elasticity modulus, loss modulus, and dynamic viscosity as functions of curing time have been obtained.

Keywords: torsional vibration technique, cure, epoxy oligomer, voscoelasticity, Ziner’s model, high elastic state, complex shear modulus, voscosity
