Abstract (EN): Adhesives used in structural high temperature space and aerospace applications must operate in extreme environments. They need to exhibit high-temperature capabilities in order to maintain their mechanical properties and their structural integrity at the intended service temperature. One of the main problems caused by the high temperature conditions is the fact that the adhesives have different mechanical properties with temperature, such as the stress-strain curve and toughness. The objective of this work was to investigate the mechanical behaviour of two different types of high-temperature adhesives, one for strength at high temperatures and one for strength at low temperatures, which will be subsequently used to design a mixed-adhesive joint suitable for use from low to high temperatures. An epoxy adhesive with a high strength at high temperatures but most likely very brittle at low temperatures would be combined with a silicone adhesive which is tough at low temperatures and does not degrade at the high temperatures even being very ductile and creep. © Galati University Press, 2012.
