Abstract
The method of molecular-dynamic modeling was applied for creating models of polyether ketone and two of its nanocomposites with fillers in the form of copper nanoparticles and with fullerene. The results of comparative study of the deformation-strength properties of these materials by means of uniaxial tension at a constant strain rate are presented. It was obtained that, when filling polyether ketone with fullerene, the elasticity value of the composite decreases by approximately two times, and in the case of filling of the same matrix with copper nanoparticles, its value increases by approximately 30%. At the same time, the average energy of intermolecular bonds of the composite with copper nanoparticles is 2.65 times greater than that of the composite with fullerene.
