Production of Metal-Polymer Composites Using Vacuum Infusion Technology weith High-Entropy Powders and Fiber-Reinforced Matrix

The class of metal-polymer composite materials consists of thin aluminum sheets and epoxy composite layers. One of the widely used types is fiber-reinforced metal-polymer composites, reinforced with fabrics such as aramid and others. Compared to similar materials, these composites offer lower specific weight, improved anticorrosion properties, and enhanced resistance to fatigue and impact. Additionally, ongoing research aims to refine and improve their properties further. One of the methods currently under active investigation for enhancing the complex physical-mechanical properties of these materials is the incorporation of functional metallic nanoparticles into their structure. Among various metallic nanoparticle fillers, high-entropy nanoparticles are considered particularly promising. This paper discusses the vacuum infusion technology used for producing metal-polymer composites based on aluminum and epoxy resin, reinforced with aramid fibers and filled with FeWNiTiAl high-entropy powders. Furthermore, it examines certain mechanical properties of the obtained samples.
