This book introduces the different advanced hybrid composite materials used in aerospace, automotive, marine, and general engineering infrastructures. It represents the current development processes and applications in aircraft, automobile, and marine structures. This book also contains test cases and their validation using a finite element approach using computer tools. The book also deals with the design approach for innovative hybrid composite materials focused on diverse engineering and non-engineering applications. A detailed review of the state-of-the-art composite materials study presented here would be of interest to scientists, academics, students, and engineers and professionals in general working in the field of advanced composite materials and structures. This book is also useful for Ph.D. research scholars to improve their fundamental understanding of advanced materials and is also suitable for master’s and undergraduate courses on composite materials.
