A study of shear strength of adhesive bonds using heat-resistant glues for bonding a thermal protection coating based on a syntactic composite material at temperatures of 20, 150, 200 °С

Based on the engineering specifications, high-temperature adhesives from various producers (designers) were selected for shear strength studies. High-temperature adhesives were considered: epoxy adhesives K-300-61 and VK-58, hot curing film adhesive VK-36, foaming adhesive UTC-9, structural adhesive CMK-22-1, epoxy metal-filled adhesives-compounds Anаterm-201, Arnterm-203, Anаterm-204, Arnterm-216, polyurethane adhesives ADV-11-1 and ADV-11-2. The paper discusses the major steps in the manufacturing process of adhesive joints based on syntactic composite material, carbon fiber, aluminum alloy D16. It provides curing modes for high-temperature adhesives. It provides a description of the surface preparation for bonding. Results of experimental studies are also provided. A comparative analysis was performed on results obtained for the ultimate shearing strength and fracture patterns of adhesive joints at temperatures 20, 150, 200 °C.
