On the Production Technology of Panels Made of Composite Materials Using Sial

Abstract

The article analyzes the most successful results of the use of metal-polymer composite materials (MPCM), reflects the advantages at the current stage of development. The analysis of the use of composite materials in the design of helicopter gliders is carried out. The use of microtubules in the manufacture of double curvature panels using MPCM is considered. Improvement of technologies in the production of structures made of MPCM. The search for optimal parameters of the technological process in the production of panels of double curvature of components based on SIAL used in the aircraft design is carried out. The optimal technological process in terms of time resources, material costs, and design weight at different levels of serial production were considered as optimization criteria in this study. Numerical modeling and optimization of workflow parameters were performed in the NASTRAN CAE system (NX). Each of the combinations of optimized process variables was determined based on numerical modeling. Analysis of the optimization results showed that the growth of parameters of the working process leads to an expansion of the area of locally optimal parameters. With optimal parameters of the working process, it is assumed that the cost of work will be reduced.
