Designing and manufacturing the working wheel from composition material

Abstract

The possible ways of using the polymer composite material (PCM) in the design of the impeller (RK) of the compressor are considered, taking into account the pecu-liarities of mechanics and manufacturing technology of composite materials. The results of the calculation of the FEM 3D model of RK from laminated carbon fiber on the PN-3M binder are given, taking into account the number of layers and the angle of exposure required to obtain the required strength values under operating conditions, in-cluding temperature conditions. The maximum stresses and deformations, as well as the displacements of the construction nodes, on the basis of which the most in-tense zones of the blade and the base of the disk were es-tablished under operating conditions, were identified. Recommendations for the creation of the Republic of Ka-zakhstan are presented and the technological possibility of its manufacture from a composite material is shown.
