Modern industries are adopting newer technologies in manufacturing sectors to sustain and excel in terms of quality at minimal cost. Because of the fast growth of technology and the requirement for outstanding mechanical, thermal, wear, and physical qualities at a cheap cost, manufacturing sectors are always on the lookout for novel materials. Because of their excellent properties and ease of manufacture, composite materials have recently become widely employed worldwide. Composite materials outperform matrix materials because they are made up of two or more components. Metal matrix composites, polymer matrix composites, and ceramic matrix composites are the three most common kinds of composites. Particularly, hybrid metal matrix or polymer matrix composites have been introduced in which two different metallic particles or fibers are reinforced to improve the properties. Automobile manufacturers such as Mercedes-Benz, Audi, BMW, and Volkswagen have previously utilized these composites to create interior and exterior elements. In addition, these types of composites are used in the construction and medical industries, and the production of briefcases and helmets.

This Special Issue aims to publicize fresh conjectural and procedural developments, significant technical applications, case studies, and study results in areas such as manufacturing and testing of advanced hybrid composites. This Special Issue invites original research and review articles on hybrid composites, which have a wide range of applications in the automotive, construction, aerospace, and biomedical industries.
