FOREIGN EXPERIENCE OF CARRYING OUT PHYSICAL AND MECHANICAL TESTS OF POLYMER COMPOSITE MATERIALS

Abstract

Currently, much attention in the field of engineering is paid to the issue of reducing the metal consumption of products. The article presents the rationale for the relevance of the production of parts and components of machines made of polymer composite materials (PCM). The possibilities of creating new industrial compositions PCM, as well as prospects for improving the accuracy when conducting their tests to determine the physico-mechanical properties. The substantiation of the choice of the methods of physicomechanical testing of PCM with the aim of determining their strength properties was carried out. The analysis of domestic and foreign standards for the conduct of physical and mechanical tests of PCM. The main differences of the requirements for carrying out physical and mechanical tests in domestic and foreign practice are determined. Methods for testing tensile and fatigue PCM samples are described. The process of analyzing test results using a software-integrated method is presented. The results of the PCM tensile test, obtained using the GOM Correlate computer program, and the graphs of the relative maximum, average, and minimum stresses during cyclic PCM fatigue tests are presented. The results of amplitude movement of stresses are presented. Using the methodology for analyzing samples used by foreign colleagues from the University of Parma (Italy), a full-scale deformation picture of the distribution of reinforcing particles on the sample surface was established.
