Enhancing the physical and mechanical properties of materials used for metal-polymer systems in structures operating under dry friction conditions through double reinforcement

Аннотация

In this article, double-reinforced heterocomposite polymer materials based on ED-20 epoxy resin were
developed, and their mechanical properties and performance under dry friction conditions were
investigated. The study utilized silk and basalt fibers, as well as kaolin as a dispersed filler, to evaluate
the composite materials' properties such as tensile strength, bending resistance, hardness, and impact
resistance. Results indicated that composites containing 25 wt.% silk and 5 wt.% basalt fiber exhibited
optimal mechanical properties and significantly enhanced impact resistance. These findings enable more
efficient operation of machine parts subjected to dry friction conditions, particularly the blades of
pneumatic transport fans.
