Abstract
Abstract
This article focuses on the results of analytical and experimental studies on the mechanical characteristics of polyurethane and composite materials developed on its basis and reinforced with aramid fabrics for their use as an elastic forming tool to manufacture various products for the aviation industry and plate heat exchanger panels made of thin sheet metal. The article presents experimental data obtained by loading polyurethane and composite materials under uniaxial compression, composes a mathematical model, and compares the results of the experiment with the theoretical dependencies obtained in solving the problem of loading the polyurethane sample via the finite element method.
