Phenomenological Modeling of Rheological Properties of Polyetheretherketones Reinforced with High Modulus Carbon in the Machining Process by a Reversible Analysis Method

Abstract

Results of modeling rheological properties (constitutive models) of composite material Victrex PEEK 90HMF20 by reversible analysis method at high-speed milling considering the direction of the reinforcing fiber are presented. Strain hardening until the moment of rupture was determined by the results of static tests of destruction at different temperatures. Coefficients of viscoplastic hardening and thermal softening were determined by the results of statistical processing of experimental milling samples of PEEK-based deformation velocity field obtained by simulation of the process of edge cutting machining in Deform 2D.
