The field of multifunctional ceramic and metal matrix composites (CMCs and MMCs) has garnered significant attention due to its potential to address a myriad of engineering and technological challenges. These materials are designed to exhibit multiple properties, such as mechanical, thermal, electrical, optical, and magnetic functionalities, alongside intrinsic properties like environmental stability and corrosion resistance. Recent advancements in nanoscience and nanotechnology have expanded the application range of these composites, making them highly relevant in diverse sectors including medicine, electronics, aerospace, and military engineering. Despite these advancements, there remain gaps in understanding the full potential of multifunctional composites, particularly in terms of optimizing their properties for specific applications and addressing environmental concerns. The development of in situ formed phases during composite processing offers a promising energy-saving approach, yet further research is needed to fully exploit these innovations and integrate them into sustainable practices.

This research topic aims to explore the recent advances in the science and technology of multifunctional CMCs and MMCs, focusing on their processing, manufacturing, microstructures, and properties. The objective is to address key questions regarding the optimization of these materials for various applications, the integration of in situ and ex situ phases, and the implications of these composites on environmental sustainability. By examining these aspects, the research seeks to contribute to the development of more efficient, cost-effective, and environmentally friendly composite materials.
