The objective of this Master thesis is to join SiC/SiC ceramic matrix composites by using an Infrared diode laser as a heating method. Currently, operational temperatures in the energy sector are constantly rising, posing significant challenges for materials. In this context, ceramic matrix composites are becoming increasingly important due to their ability to withstand high temperatures, to their “quasi-ductility”, and their low density. Therefore, it is essential to study effective methods for creating joints between these materials. Since SiC/SiC do not melt, the joint will be made using a third material, the joining material. This Master thesis will focus on two different joining materials: SAY (Silica-Alumina-Yttria based glass-ceramic) and YAG (Yttrium-Aluminum Garnet).
