Rheological behaviour and thermal dilation effects of alumino-silicate adhesives intended for joining of high-temperature resistant sandwich structures

The study is concerned with inorganic adhesive layers located between the CMC composite skin and the Si–O–C ceramic foam core of sandwiches intended for high-temperature use. Two types of alumino-silicate 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 °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.

Preparation,structural evolution,and performance of heat-resistant organosilicon polymer adhesives for joining SiC ceramics

There is an urgent need for heat-resistant adhesives with high bonding strength in order to able to fabricate large and complex SiC components for aeronautical and astronautical applications. In this study, heat-resistant organic adhesives prepared using an organosilicon polymer and inorganic additives (B₄C and SiO₂) were used successfully to bond SiC ceramics. The prepared adhesives were characterised through shear strength tests as well as using thermogravimetry-differential scanning calorimetry, Fourier-transform infrared spectroscopy, X-diffraction analysis, and scanning electron microscopy. The adhesives exhibited high room-temperature shear strengths (greater than 15 MPa) after being subjected to heat treatments at 200–1200°C. Further, the high-temperature shear strengths of the adhesives at 200, 400, 600, 800, and 1000°C were 10.5, 10.1, 7.7, 8.6, and 8.4 MPa, respectively. The high performance of the adhesives indicated that they should be suitable for joining SiC-based materials for use in high-temperature applications.
