It is known that composites have insufficient transversal strength and rigidity, and low longitudinal shear modulus, compression and shear strength. This book describes methods to avoid these disadvantages by hybridization and spiral reinforcement of composites at the micro-level during the production stage. Mathematical models and design methods have been developed for various composites. The authors discuss the technology of spiral reinforcement and fillers, the structures and properties of spirally reinforced composites, binders, the manufacture of such composites, and the application of new materials and constructions. This informative text will be of interest to researchers, teachers and students in academia and also to industrial scientists and engineers involved in the development and application of new materials.
