The book "Advanced Composite Materials" offers a comprehensive introduction to the world of high-performance polymer composite materials. These materials are characterized by their exceptional combination of high strength and stiffness, surpassing structural metals and alloys in terms of weight. The content of the book addresses the essential components that must be considered in the design of composites, including surface chemistry, analyses and tests, as well as structure-property relationships, with a particular focus on compressive strength and damage resistance. Additionally, novel tests, especially open hole compression tests, are presented, promising improved reliability of composite performance. This publication provides a current overview of advanced areas of composite technology and includes a comprehensive literature review up to recent times, covering thermoplastic prepregs and key application areas.
