DYNAMIC THREE-POINTS-BENDING TEST MODE OF TWO AMORPHOUS POLYMER MATERIALS (PMMA, PC) FOR THEIR VISCOELASTIC AND MECHANICAL CHARACTERIZATION

This paper presents an approach to classifying amorphous polymer materials. Temperature is classification involves the determination of mechanical and viscoelastic characteristics considered a descriptive variable clarify specific field practical applications polymers. according reference temperature characterizing behaviour The polymers such as methyl poly-methacrylate (PMMA), polycarbonate (PC) imide poly ether (PEI) are determined through three-point dynamically embedded test carried out in adiabatic close enclosure. complex dissipative or conservative modules represented. results obtained show that fluidity index these materials linked their viscosity, which determining property decisive for choice technique application material. Our method measuring properties therefore, principle, comparable techniques used industrial development.
