It significantly improved the mechanical properties of composites and increased their ability to degrade after the end of service life. Aerosil-filled polyurethane was obtained for use as a solid-state laser element, which characterized by increased thermal stability and elasticity, high transparency in the visible region and effective shielding of UV radiation. A new approach to improving the damping properties of materials is proposed, which consists in the construction of two-layer polyurethane composites in different ways: formation of two layers consistently or bonding of individual films.   Product Description popup.authors Ignatova Taisa D.
