**Preface to "Fabrication of Carbon and Related Materials/Metal Hybrids and Composites"**

This Special Issue covers various aspects of materials science and engineering in the field of the fabrication of hybrid and composite materials. It mainly focuses on the novel developments in and new processing methodologies for the fabrication and modification of carbon and related hybrid and composite materials for different applications. It consists of sixteen research papers and one review article describing diverse research topics. The contributions of this Special Issue may be classified into four groups: the first concerns fabrications of new composite and hybrid materials of the different allotropies of carbon, such as carbon fibers, carbon nanotubes and graphene; the second group considers the synthesis and properties of new polymeric composite and hybrid materials with various applications due to their electrical, mechanical and antimicrobial activities; the last group is strongly related to a discussion on alloys and metal matrix composites and their welding properties. Some of the articles generally contain the results of calculations and are compared with experimental observations. The results presented in the articles collected in this Special Issue clearly demonstrate that the carbon-based hybrid and composite materials are clearly very important in the field of advanced functional materials.

We would like to thank all authors whose contributions are included in this Special Issue for their excellent work, and for their inspiring and interesting articles.
