Problems Associated with Design and Manufacturing of Parts Based on Particulate-Filled Polymer Composites

In the article, issues related to engineering and manufacturing design of machine-building parts from particulate-filled polymer composites are considered in the light of achieving the required strength and technological characteristics. A technique is proposed to optimize the process of choosing a rational composition of particulate-filled polymer composites for each specific product based on the estimation of the specific adhesive energy and the effective viscosity of the material in the uncured state. The specific adhesive energy is estimated on the basis of the formation of an oriented surface layer at the binder - solid body interface as well as a structure of representative volume. The calculated energy and technological characteristics are compared with the results of strength testing. The comparison showed that a change in the specific adhesive energy was reflected in the change of strength characteristics of the particulate-filled polymer composite material depending on its composition. Thus, the proposed technique provides a comprehensive assessment of particulate-filled polymer composite from the standpoint of strength and technological characteristics, based on the data on its granulometric composition, filling ratio and type of binder.
