Abstract
Abstract The work is aimed at creating new scientifically proven technical and technological solutions for the development and implementation of additive manufacturing of products from heat-resistant reinforced composites allowing samples to be created of new equipment and structural products for the aerospace industry surpassing existing analogues in their properties. Samples of the binder used to obtain composites were studied. Studies were carried out using IR spectroscopy with Fourier transform, and a comparison of the bands of stretching and deformation vibrations of the studied sample and classical polydimethylsiloxane was carried out. The dry residue after combustion of the sample was studied using transmission electron microscopy. It was shown that the sample is polydimethylsiloxane filled with silicon dioxide. Chromatograms and molecular-weight characteristics of polydimethylsiloxane were obtained. The soluble part of the sample was no more than 35% in the case of using benzene and tetrahydrofuran as solvents.
