Two types of aluminosilicate adhesives (mastics) were tested for use as the bonding layer. The rheological properties of adhesive and its dimensional changes during high-temperature curing play a key role in terms of successful manufacture and subsequent use at high temperatures. In order to characterise these properties, specimens consisting only of the dried adhesive were subjected to compression tests conducted at increasing temperature from 300 to 1000 degrees C. These experiments were carried out via the application of two loading modes using both the static pre-load and cyclic loading methods. The above results were compared with thermal expansion records determined from fully-cured adhesives. In addition to the above investigation, the mechanical properties of the adhesive joint were measured employing both the DCB and shear tests.
