Nature constantly combines various materials into composite materials to achieve improved properties and synergy effects. In the field of materials science, this has been most successfully and advanced in the innovative group of composite plastics, known as fiber-reinforced plastics. A material is constructed from individual components, the high-strength fibers and the matrix, which only fully forms during processing. Successful optimization requires in-depth knowledge of the properties of the components and their interactions. The goal of an application must be kept in mind, as well as potential influences during processing and the specific behavior during the use of the finished component. Therefore, the book covers the material science and mechanical fundamentals of fiber-reinforced plastics, as well as the properties of the individual components.
