Composite materials have been at the basis of many significant breakthroughs in various industrial applications, particularly in aerospace structures, over the past forty years. Their high strength-to-weight and stiffness-to-weight ratios are the main material characteristics that attract the attention of the structural and design engineers. This work provides comprehensive analysis of the contemporary theoretical models at the micro- and macro levels of material structure, detailing practical methods and approaches, experimental results, and optimisation of composite material properties and structural component performance that can be used by researchers and engineers. It consists of twelve chapters progressively covering all structural levels of composite materials from their constituents through elementary plies and layers to laminates and laminated composite structural elements. Detailed physical mathematical coverage of complex mechanics and analysis required in actual applications - not just standard homogeneous isotropic materials Environmental and manufacturing discussions enable practical implementation within manufacturing technology, experimental results, and design specifications. Discusses material behavior impacts in-depth such as nonlinear elasticity, plasticity, creep, structural nonlinearity enabling research and application of the special problems of material micro- and macro-mechanics
